Повний текст джерелаPredicting soil strength from hyperspecral imagery enables amphibious planners to determine trafficability in the littorals. Trafficability maps can then be generated and used during the intelligence preparation of the battlespace allowing amphibious planners to select a suitable landing zone. In February and March 2010, the Naval Research Laboratory sponsored a multi-sensor remote sensing and field calibration and field validation campaign (CNMI'10). The team traveled to the islands of Pagan, Tinian, and Guam located in the Marianas archipelago. Airborne hyperspectral imagery along with ground truth data was collected from shallow water lagoons, beachfronts, vegetation, and anomalies such as World War II relics. In this thesis, beachfront hyperspectral data obtained on site was used as a reference library for evaluation against airborne hyperspectral data and ground truth data in order to determine soil strength for creating trafficability maps. Evaluation of the airborne hyperspectral images was accomplished by comparing the reference library spectra to the airborne images. The spectral angle between the reference library and airborne images was calculated producing the trafficability maps amphibious planners can use during the intelligence preparation of the battlespace.

Повний текст джерелаA presente pesquisa trata da avaliação da resistência ao arrancamento de grampos em solo residual de gnaisse. Foram realizados ensaios de arrancamento em uma obra de solo grampeado executada em um maciço de solo residual de gnaisse. A resistência ao arrancamento foi avaliada em 4 cotas diferentes ao longo do perfil de escavação. Foram realizados 8 ensaios de arrancamento em grampos de 4m de comprimento. Quatro ensaios foram executados em grampos instrumentados com strain-gages, para avaliar a distribuição das cargas de tração durante os estágios de carregamento. Foram também realizados ensaios de cisalhamento direto no solo e na interface solo/cimento para avaliação das propriedades mecânicas destes materiais. Amostras indeformadas foram coletadas imediatamente à frente dos furos de instalação dos grampos ensaiados garantindo uma maior representatividade dos materiais. Uma relação semi-empírica é proposta para se avaliar a resistência do solo e da interface solo/nata de cimento, obtidos em ensaios de cisalhamento direto no laboratório. Os resultados obtidos nesta pesquisa são comparados com ensaios realizados por outros autores, em encostas de solos residuais de gnaisse e empregados para validação da relação desenvolvida.
The present research presents an evaluation of the pullout resistance of nails in residual gneissic soil. Pullout tests were carried out in 4 different levels of the nailed wall with nails 4m long. Four tests were carried out in strain-gauged nails for evaluating the tension distribuition along the nail. A series of direct shear tests in soil specimens and in the soil/grout interface were also performed for obtaining the mechanical properties of these materials. Undisturbed samples had been collected very close to the pull-out test locations. A semi-empirical relation is proposed for evaluating the pullout resistance of nails, based on the shear strenghth parameters of the soil and of the soil/grout interface from laboratory direct shear tests.

Повний текст джерелаSoil consistency limits, soil water status, applied pressure and organic matter contents were used to predict shear strength, penetration resistance and water retention characteristics of compacted soils, with the aim of meeting the widespread demand for possible techniques of soil compaction prediction.
Soil compaction increased the ability of the soils to retain moisture, increased penetration resistance, shear strength and decreased the available water capacity of soils. On the other hand, organic matter increased the ability of the soils to retain moisture, expanded the available water capacity and decreased the penetration resistance and shear strength of compacted soils.
Although soil compaction increased the stem diameter of bush bean; the height, yields and root dry matter of the crop decreased with higher compaction levels. On the contrary, higher organic matter levels increased the plant and yield parameters of the crop.

Organic soils are formed continuously as matter from deceased organisms – mainly plants – is deposited in wet environs and decomposes. Organic soils are most commonly found in swamps, marshes, and coastal areas. These soils make poor foundation materials due to their low strengths. Deep mixing, or soil mixing, involves introducing a binder like Portland cement or lime into soil and blending the soil and binder together to form columns or blocks. Upon mixing, cementitious reactions occur, and the soil-binder mixture gains strength as it cures. Deep mixing may be performed using either a dry binder, known as dry mixing, or a binder-water slurry, referred to as wet mixing. Deep mixing may be used to treat either inorganic or organic soils to depths of 30 meters or greater. Contractor experience has shown that deep mixing is one of the most effective methods of improving the strength of organic soils. Lab-scale studies (by previous researchers) of wet mixing of inorganic soils have found that the strength of soil-binder mixtures can be expressed as a function of mixture curing time and curing temperature, as well as the quantity of binder used, or binder factor, and the consistency of the binder slurry. No corresponding expression has been generated for wet mixing of organic soils, although many studies on the subject have been performed by previous researchers. The goal of this research was to generate such an expression for one organic soil. The soil used was made of sphagnum peat moss, an organic material commonly found in nature, and an inorganic clay used by previous researchers in studies of deep mixing in inorganic soils. The binder used in this research was a Portland cement. For this research, 43 unique soil-binder mixtures were manufactured. Each mixture involved a unique combination of soil organic matter content, binder factor, and binder slurry consistency. After a soil-binder mixture was made, it was divided, placed into cylindrical molds, and allowed to cure. The temperature of the curing environment of the mixture was monitored. Mixture compressive strength was assessed after 7, 14, and 28 days of curing using two cylindrically molded specimens of the mixture. Data on mixture strength was then evaluated to assess whether it could be expressed as a function of the variables tested. iv This research determined that the strength of at least some organic soils improved with wet mixing can be expressed as a function of soil organic matter content, binder factor, binder slurry consistency, and mixture curing time and curing temperature. The function will likely prove useful to deep mixing contractors, who routinely perform lab-scale deep mixing trials on samples of the soils to be improved in the field. Assuming wet mixing is used, the results of the trials are used to select values of binder factor and binder slurry consistency for the project. The function generated from this research will allow deep mixing contractors to select these values more reliably during the lab-scale phase of their work.
