A series of centrifuge liquefaction tests have been conducted at C-CORE’s geotechnical centrifuge facility: two on variable soil and one on uniform soil deposits. A single storied frame structure resting on two strip footings was also placed on that soil deposit. Experimental results such as accelerations, excess pore water pressures (EPWP) and settlements were monitored throughout the tests. R...

A large-scale trial embankment provided with partially penetrating prefabricated vertical drains (PVD) was installed in consolidating marine clay deposits at East-Port said industrial zone project Egypt. The constructed a bottom area of 150x150m and height 5.5m to evaluate the efficiency improvement system verify design parameters. An intensive instrumentation built-up including shallow settlem...

Climate change may affect the ability of soil-based onsite wastewater treatment systems (OWTS) to treat wastewater in coastal regions of the Northeastern United States. Higher temperatures and water tables can affect treatment by reducing the volume of unsaturated soil and oxygen available for treatment, which may result in greater transport of pathogens, nutrients, and biochemical oxygen deman...

Directional variability of spatial correlation is observed in natural soils due to their depositional characteristics and it influences the response of structures founded on these deposits. Nonetheless, the results presented in most of the available literature are based on the assumption of either isotropic spatial correlation or perfect spatial correlation of soil properties in horizontal and ...

Strategies for sampling shallow soils at hazardous waste sites are employed primarily to evaluate levels and distributions of contamination. The ensuing analyses of potential public health impacts are therefore dependent on the sampling design rather than having the sampling design based on the data needs for evaluating potential public health impacts of shallow soil contamination. We define a ...

In recent decades, the human demand for mineral resources has increased dramatically, and mining of shallow deposits basically been completed. The prospecting direction turned to concealed deposits. For this reason, various penetrating geochemical methods have developed find minerals a series exploration techniques proposed. At same time, use gene as new technique presented in years is feasible...

For tree species adapted to shallow soil environments, rooting strategies that efficiently explore rock fractures are important because soil water depletion occurs frequently. However, two questions: (a) to what extent shallow soil-adapted species rely on exploring rock fractures and (b) what outcomes result from drought stress, have rarely been tested. Therefore, based on the expectation that ...
