Повний текст джерелаGrus i form av krossat bergmaterial används i stor utsträckning som obundna bär- och förstärkningslager inom tranportinfrastrukturen och spelar där en viktig roll för verkningsätt, drift och underhåll. Det finns emellertid begränsad kunskap om de fundamentala mekanismerna på partikelnivå (d.v.s. enskilda gruskorn), mekanismer som styr det makromekaniska verkningssättet. Områden såsom väg- och järnvägsbyggnad bygger fortfarande väsentligen på empiriskta baserade modeller p.g.a. dessa materials komplexa uppträdande under belastning. Denna komplexitet beror delvis på den diskreta naturen hos problemet vilket innebär att traditionell matematisk modellering som vore materialen homogena och kontinuerliga, blir inadekvat. Mot denna bakgrund utgör den s.k. diskreta elementmetoden (DEM) ett numeriskt alternativ för att studera verkningssätt hos diskreta system där man explicit beaktar mekanismerna på partikelnivå. Denna avhandling, som baseras på tre vetenskapliga bidrag, syftar till att ge mikromekaniska insikter vad gäller effekten av olika partikelstorlekar på bärförmågan hos grusmateral och dess inverkan på styvhet och motstånd mot permanenta deformationer. Båda dessa parametrar påverkas kraftigt av spänningsnivån och kan studeras genom triaxialförsök. För att undersöka detta studerades med hjälp av DEM binära blandningar av elastiska kulor – den enklaste modellen av grusmaterial med språng i fördelningskurvan – som utsattes för axialsymmetrisk belastning. Denna modell kan i sin tur ses som en förenkling av mer komplexa blandningar. Inledningsvis studerades effekten av finpartikelinnehållet på partikelkontakternas kraftöverföring. Resultaten användes för att klassificera olika typer av skelettstrukturer i grusmaterialet där den finare och den grövre fraktionens roller kvantifierades med utgångspunkt från kraftöverföringen i stället för från det makromekaniska verkningssättet. Resultaten visade en korrelation vad gäller verkningssättet mellan numeriska blandningar och grusmaterial, där de numeriska blandningarna kunde reproducera några av grusmaterials viktigaste kännetecken vad gäller spänningsberoendet för styvheten vid avlastning och motståndet mot permanent deformation. Vidare visades att styvheten kunde bestämmas ur första belastningscykeln vilket underlättar att övervinna de begränsningar avseende beräkningstid som annars förknippas med DEM. God överensstämmelse mellan grusmaterialets skelettstruktur och verkningssätt kunde också observeras. Generellt observerades högre styvhet och mindre permanenta deformationer för interaktiva skelettstrukturer medan det motsatta gällde för instabila strukturer. Numeriska blandningar av elastiska kulor är långt från verkliga grusmaterial, för vilka ett stort antal ytterligare faktorer måste beaktas. Icke desto mindre är det författarens övertygelse att detta arbete ger insikter i grusmaterialets skelettstruktur och dess effekter på det makromekaniska verkningssättet hos grusmaterial.

Soil piping is a hydraulic and geotechnical phenomenon that soil hydraulic fails due to seepage. Soil piping can happen in geotechnical engineering and ecosystem. An upward seepage testing system is developed to study the seepage failure of soil. The testing system consists of a transparent acrylic permeameter, a constant head device and a data acquisition system. Using this test apparatus, a series of experiments on uniform sand and gap-graded sand are carried out to observe the process of seepage failure of specimen and to determine the critical hydraulic gradient. This study found the seepage failure mode is depended on the internal stability of soil which mainly depends on the grain size distribution and can be assessed using stable criteria. Test result shows seepage failure of uniform sand (internally sable soil) typically experiences an expansion of specimen thickness and the liquefaction of specimen, which is associated with the condition of effective stress equals zero. Seepage failure of gap-graded sand (internally unstable soil) is related to the internal erosion of fines which shows the finer particles in specimen will be vigorously eroded out with upward seepage flow, but the coarser particles remain comparatively stable. Further, the critical hydraulic gradients icr of soil obtained from test are compared with the predicted icr using theoretical equation proposed by Terzaghi. It is found the values of icr of uniform sand range from 0.89 to 1.21 which are close to the predicted icr. The values of icr of gap-graded sand range from 0.27 to 0.43 are far lower than the predicted icr. A database of icr of soil is compiled from this study and relevant literatures, and is used to compare different icr prediction methods and identify a best prediction method. Comparison result shows there is no a best methods can accurate predict the icr for all types of soils, but Terzaghi’s equation can predict the icr well of soil which satisfies the stable criterion proposed by Kenny and Lau (1985). Finally, this study is expected to provide the contribution in geotechnical engineering for a better understanding of seepage failure of soil and their critical hydraulic gradient.

Suffusion is a type of the internal erosion which involves in a selective erosion of the fine particles through the soil skeleton. To better understand the mechanism of the erosion in various soil types and evaluate the improvement of the fiber-reinforced soil under suffusion, a total number of 12 upward seepage tests on three grain size distributions (i.e., two uniform soils and one gap-graded soil) were conducted. The objectives of this study are to investigate the influence of fiber parameters, fiber content and length, on hydraulic behavior and failure modes in fiber-reinforced soil (FRS) and to establish a modified criterion to assess the internal stability of FRS. Experimental results indicates that the inclusion of the fiber can significantly decrease the permeability k and increase the Forchheimer coefficient β. Under the variation of the fiber content and length, the failure mode of suffusion, classified as internally unstable soil, changed to the failure mode of suffosion, classified as internally stable soil. With the increase in fiber content, the onset of the erosion in fines and the shift into transition flow zone were generally postponed, whereas the increase of the fiber length presented minor improvements. For suffusion, the critical hydraulic gradient of failure was increase majorly related with the fiber content; however, the which for the suffosion was increase with the fiber length. In addition, the results of modified criterion in unreinforced cases are in a good agreement with the experimental data in literatures and the which in reinforced cases owns a degree of conservatism.
