Pełny tekst źródłaENGLISH ABSTRACT: Geotechnical engineering is a relatively young field of engineering and one in which there are still many unanswered questions and gaps in our knowledge. Added to this, the geotechnical materials on each new site on which geotechnical work is undertaken are the unique product of many influences including geology, geomorphology, climate, topography, vegetation and man. There is thus plenty of scope for innovation. This dissertation describes the contributions made to Geotechnical Engineering in South Africa by the Candidate over a period of close on 40 years. It describes the three-step process followed in the majority of these contributions. Step one is the identification of a problem that requires investigation, the application of new techniques or simply the consolidation of existing knowledge. Step 2 is the investigation of the problem and the development of a solution. Step 3 is sharing the outcome of this work with the profession by means of publications, by presentations at seminars and conferences or by incorporation into standards / codes of practice. Part 1 of the dissertation describes the exciting environment in which geotechnical engineers operate. This environment is characterised by openness and cooperation between practitioners of geotechnical engineering, be they geotechnical engineers, engineering geologists, contractors, suppliers or academics. This part also explores the parallels in the roles played by academics and practitioners and how each can contribute to the advancement and dissemination of knowledge. Part 2 describes contributions made in various fields including problem soils (dolomites, expansive clays, uncompacted fills, etc.), lateral support, pile design and construction, health and safety, and cooperation with international organisations. Part 3 describes the Candidate's involvement in the introduction of limit states geotechnical design into South African practice culminating in the drafting of SANS 10160-5 on Basis of Geotechnical Design and Actions. It also describes the Candidate's work with the ISSMGE Technical Committee TC23 dealing with limit states design. Part 4 deals with the Candidate's contribution to other codes and standards and his role on various committees of the Engineering Council of South Africa and the South African Bureau of Standards. The final part of the dissertation provides an overview of the process followed in making such contributions, highlighting the role played by curiosity and a desire to share the knowledge gained with others in the profession. It continues by identifying work that still needs to be done in many of the areas where contributions have been made and concludes with a statement of what the candidate would still like to achieve during the remainder of his career. The Candidate gratefully acknowledges the generous opportunities afforded to him by his colleagues at work and the invaluable guidance and mentorship received from fellow professionals in academia and practice.
AFRIKAANSE OPSOMMING: Geotegniese ingenieurswese is 'n relatiewe jong wetenskap en een met vele kennisgapings en waarin daar nog talle vrae onbeantwoord bly. Daarby is geotegniese materiale uniek tot elke terrein waarop werk aangepak word en die produk van 'n kombinasie van prosesse; insluitend geologie, geomorfologie, klimaats toestande, topografie, plantegroei en menslike aktiwiteite. Daar is dus nog ruim geleentheid vir innoverende bydraes. Hierdie verhandeling beskryf die Kandidaat se bydraes tot Geotegniese Ingenieurswese in Suid-Afrika oor die afgelope 40 jaar. Dit beskryf 'n drie-voudige benadering wat in die meeste van die bydraes gevolg is. Die eerste stap is om die probleem te definieer en te omskryf in terme van die ondersoek wat geloods moet word, asook die noodsaaklikheid vir die ontwikkeling van nuwe tegnologie teenoor die konsolidasie van bestaande inligting. Tydens die tweede stap word die probleem ondersoek en 'n oplossing ontwikkel. Die derde stap is om die resultate te deel met die geotegniese bedryf by wyse van publikasies, voorleggings by konferensies en seminare, en insluiting in praktykkodes en standaarde. Deel 1 beskryf die opwindende werksomstandighede waarbinne geotegniese ingenieurs hul bevind. Dit word geken aan die ope samewerking tussen belanghebbende partye; onder andere ingenieurs, ingenieursgeoloë, kontrakteurs, verskaffers en akademici. Deel 1 beklemtoon ook die parallelle rolle wat vertolk word deur akademici en praktiserende ingenieurs en hoe beide partye bydraes maak tot die ontwikkeling en verspreiding van tegnologie. Deel 2 beskryf die Kandidaat se bydraes tot verskeie navorsingsvelde; waaronder probleemgrondtoestande (dolomiet, swellende kleie, ongekonsolideerde opvullings ens.), laterale ondersteuning, ontwerp en konstruksie van heipale, beroepsveiligheid, en samewerking met internasionale organisasies. Deel 3 beskryf die Kandidaat se betrokkenheid by die bekendstelling van limietstaat geotegniese ontwerp in die Suid-Afrikaanse bedryf wat uitgeloop het op die samestelling van SANS 10160-5 Basis of Geotechnical Design and Actions. Dit beskryf ook die Kandidaat se samewerking met die ISSMGE Technical Committee TC23 wat te make het met limietstaat ontwerp. Deel 4 beskryf die Kandidaat se bydraes tot ander kodes en standaarde en die rolle wat hy vertolk het op verskeie komitees van die Suid-Afrikaanse Raad vir Ingenieurswese asook van die Suid-Afrikaanse Buro van Standaarde. Die laaste deel van die verhandeling bied „n oorsig oor die proses wat gevolg is in bostaande bydraes met die klem op die rol van weetgierigheid en die begeerte om sulke kennis te deel met ander belanghebbendes. Om af te sluit, identifiseer die Kandidaat oorblywende tekortkominge in baie van die vraagstukke waar hy bydraes gelewer het en gee 'n opsomming van wat hy graag nog sal wil bereik tydens die verdere verloop van sy loopbaan. Die Kandidaat gee met dank erkenning aan sy kollegas vir die ruim geleenthede wat hom gebied is en die waardevolle leiding en mentorskap wat hy ontvang het van mede praktiserende ingenieurs en akademici.

Pełny tekst źródłaUttjänta däck är ett avsättningsproblem avseende de stora volymerna som produceras varje år. Däckklipp produceras främst med avseende på att reducera transportvolymen av insamlade däck. Inom EU har det införts ett förbud mot att deponera däck och däckklipp för att dels reducera den totala volymen avfall som deponeras och dels för att uppmuntra återvinning av däckmaterial. Den huvudsakliga avsättningen för uttjänta däck har fram tills nu varit energiåtervinning, främst inom cementindustrin.Däckklipp har intressanta tekniska egenskaper som fördelaktigt kan utnyttjas i anläggningstekniska tillämpningar. Karakteristiska egenskaper för däckklipp är låg densitet, hög elasticitet, låg styvhet, hög dränerande och hög värmeisolerande förmåga. Kombinationen av dessa egenskaper möjliggör tekniskt innovativa lösningar inom anläggningsbyggande.Det övergripande syftet med avhandlingen har varit att beskriva och utvärdera däckklipp som ett anläggningsmaterial ur både teknisk och miljömässig synvinkel. Arbetet har inkluderat både laboratorie- och fullskaleförsök för att utreda tekniska, miljö- och anläggningstekniska egenskaper. Vidare har det aktuella kunskapsläget om däckklipp som anläggningsmaterial utvärderats och presenterats.I laboratorieförsök har tekniska egenskaper med fokus mot packnings- och kompressionsegenskaper för däckklipp undersökts. I ett fältförsök har en vägkonstruktion med däckklipp som lättfyllnads- och tjälisoleringsmaterial byggts och utvärderats under fyra år. I laboratorieförsök har lakningsegenskaper för däckmaterial och miljöövervakningsprogram för tre olika konstruktioner utvärderats.Baserat på laboratoriestudier har en utvärderingsmodell för spännings-töjningsegenskaper och beräkning av kompression föreslagits. Rekommendationer för anläggningsteknik och vägdimensionering presenteras baserat på utvärderingen av vägkonstruktionen.Slutsatser baserat på lakningsstudierna i laboratoriemiljö och utvärderingen av miljöövervakningsprogrammen för fältkonstruktionerna är att de metaller som främst lakar ut är zink och järn och att lakningen av de studerade organiska föreningarna, d.v.s. PAH och fenoler, är låg. Från ett miljöperspektiv bör fokus flyttas från PAH mot organiska föreningar som har hög mobilitet och där kunskapsläget är lågt. Slutsatsen i detta arbete är att PAH-föreningar inte utgör ett föroreningsspridningsproblem för konstruktioner med däckklipp.Tillämpningar där däckklipp framgångsrikt har använts som konstruktionsmaterial är t.ex. i dräneringslager i deponier, i travbanor, och i paddockar. Användningen av däckklipp i travbanor och paddockar är särskilt intressant eftersom belastningen på hästarnas ligament kan minskas.Potentialen att använda däckklipp som ett anläggningsmaterial är stor. Eftersom tillgången är begränsad finns det en möjlighet att styra användningen till de lösningar där materialet används optimalt, både tekniskt och miljömässigt, och ändå avsätta all tillgänglig volym uttjänta däck.

Pełny tekst źródłaThe engineering behaviour of carbonates differ substantially from quartz based soils. A review of the literature was undertaken in an attempt to identify relevant parameters which could provide the basis for an improved engineering classification. Carbonate content, cementation, crushability, particle size distribution and Atterberg limits were found to be relevant to engineering behaviour of carbonates, and should be included. The maximum obtainable void ratio (emax), which is related to the particle shape distribution, has been proposed as an additional index for carbonate sands. Results from direct shear tests showed that this parameter correlates well with crushability and compressibility. It is recommended that this parameter (emax) as determined in the test devised by Kolbuszewski (1948), should be adopted as an index property for classifying carbonate sands.

Pełny tekst źródłaLes digues des résidus miniers sont des ouvrages géotechniques conçus pour offrir un stockage adéquat et sécuritaire des résidus et ce pendant et après la fin de la vie de la mine. La conception des digues à résidus est actuellement basée sur les méthodes d'équilibre limite (LEM) qui sont utilisés pour calculer les facteurs de sécurité de la stabilité des pentes sous diverses charges opérationnelles. Le facteur de sécurité minimal obtenu à partir de ces analyses est considéré comme facteur de sécurité de conception. Ils sont présentement utilisés dans la conception géotechnique. Cependant, LEM a des lacunes notamment le manque d'information sur la déformation d'une digue et de l'interaction entre les contraintes effectives et la pression interstitielle. Ainsi, les techniques de modélisation numérique avancées qui considèrent le couplage hydro-mécanique survenant dans la structure de la digue ont été développées. Ces modèles procurent un aperçu plus précis du comportement géotechnique de la digue à résidus. Cependant, les deux approches LEM et modélisation numérique sont déterministe. Par conséquent, ces approches ne tiennent pas compte de l'incertitude inhérente aux propriétés des matériaux de construction et ceci est un fait bien connu par l'ingénieur géotechnicien et pourtant ceci doit être abordé.Dans cette thèse, les approches d'analyse stochastiques tels que le Monte Carlo (MC) sont adoptées pour étudier l'effet de l'incertitude inhérente aux propriétés du matériau sur le coefficient de sécurité. Les deux LEM et les modèles numériques hydro- mécaniques couplés sont d'abord développés et après les résultats des modèles déterministes sont compilés. Ces derniers sont ensuite comparés aux résultats obtenus à partir des analyses stochastiques.Une étude de cas d'une nouvelle conception d'une digue à rétention d'eau à résidus avec des données géotechniques bien documentées est adoptée dans cette étude. Tout d'abord, l'analyse LEM a été poursuivi et suivi par une analyse de sensibilité pour déterminer les paramètres les plus influents sur le facteur de sécurité de la conception.Ensuite, un model couplé d'hydro-mécanique a été développé avec FLAC2D dans lequel la séquence de construction a été simulée en sept étapes. Le coefficient de sécurité (FOS) a été calculé à la fin de chaque étape en utilisant la technique de réduction de la résistance (SRT). Par la suite, la méthode d'estimation ponctuelle (PEM) a été utilisée pour obtenir la probabilité d'un rendement insatisfaisant en tenant compte de l'angle de base de la digue, de la friction, de la cohésion et de la perméabilité comme variables stochastiques. Le coefficient de variation des propriétés du matériau a été varié et ses conséquences sur la probabilité ont été enregistrées. Ensuite, la méthode de MC a été adoptée pour calculer la probabilité de rendement insatisfaisant de la digue à résidus ainsi que sa fiabilité. Par ailleurs, l'effet de la modification de la fonction de densité de probabilité (PDF) du paramètre d'entrée stochastique sur la fiabilité de sortie a encore été analysé. En outre, l'effet du hasard au niveau local a été étudiée en utilisant le hasard Monte-Carlo (RMC) et la méthode par rapport à la sortie de la méthode de MC. Enfin, l'effet du coefficient de corrélation entre l'angle de friction du noyau et la cohésion sur la fiabilité de la digue a été analysé. Ceci a été suivi d'une analyse stochastique avancé à l'aide de la méthode MC qui comprenait une troisième variable stochastique qui est la perméabilité du noyau. L'incorporation de paramètres à la fois mécaniques et hydrauliques en tant que variables stochastiques ont réduit la fiabilité de la digue, ainsi, mettant en évidence l'impact de l'analyse stochastique hydro-mécanique avec l'approche hybride. Les résultats de toutes les analyses sont présentés dans la thèse suivante ainsi que les découvertes dans la conclusion.

Pełny tekst źródłaEngineers are often faced with construction of pavement structures over soft and compressible subgrade. Such conditions render the structures unable to withstand required design loads and thus are susceptible to high settlements associated with excessive distress leading to pavement damage. The use of imported quality fill to improve the load-bearing capacity of the subgrade has limited benefits, which leads to the necessity of an alternative construction approach to attain the necessary strength of the soil structure. The use of geosynthetics in soil offers a better alternative to improvement of the soil's stability. This research was conducted to determine the degree of improvement of the load-bearing capacity and reduction in settlement due to geosynthetic reinforcement of a soft clay overlain by granular material.

This study is trying to put different contents of nano-clay into the laterite to research what’s the influence of nano-clay to the physical properties and the engineering behavior of laterite; and also try using nano-clay as a stabilizer of arenaceous trench excavation to research the stabilization of trench excavation. There’re following test results from this research: (1)The liquid limitation, plastic liquid and plasticity index of laterite are all increased gradually by adding different content (amount) of Nano-clay. The more liquid limitation, the more compression properties, and when the plasticity index increasing, it means the adsorbed water layer is more thicker and the permeability is more lower.(2)The unconfined compression strength is increased significantly when adding the Nano-clay into laterite but the unconfined compression strength wound not be increased when the content of Nano-clay from 0.5% increasing to 2%. The most unconfined compression strength could be 2.2 times better than pure laterite.(3)The coefficient of permeability is reduced gradually by adding the content (amount) of nano-clay.(4)Both the 6% of nano-clay slurry(the viscosity is 17.68 seconds) and 7% of bentonite slurry(the viscosity is 18.91 seconds) could have the stabilization of trench excavation.

Because the usable land in Taiwan is limited, and the population grows up so fast, high-rise buildings with deep excavation and hillside inhabitation are constructed in urban and mountain areas. Deep excavation in soft soil, lateral diaphragm wall deflection is usually a major concern. Heavy rains that accompanied typhoon always cause severe debris flows and landslides. In addition, due to common occurance of earthquake, considerable amount of damages have been caused by earthquake induced liquefaction. How to make a safe design and construction and minimize damage is of utmost importance in a geotechnical engineering project. The feasibility of using artificial neural networks (ANN) for assessing geotechnical engineering problems have been examined by many researchers .The first objection of this research is to predict diaphragm wall deflection by applying the learning ability of back-propagation ANN to develop a forecast model, based on collected ten top-down cases. The results of this research indicate that ANN can reasonably predict the maguitude, as well as the location of maximum deflection of a diaphragm wall. Then a neuro-fuzzy system is developed,and the Chi-Chi earthquake data as well as other reported data are used to evaluate earthquake induced liquefaction potentials. With the help of case studies, it is shown that proposed model has less error rate than conventional empirical and traditional ANN methods. Finally, the proposed neuro-fuzzy model is used to investigate its applicability and practicalibity for debris flow. The results demonstrate that the proposed neuro-fuzzy model is applicable and effective tool for debris flow warning system.
