Otherwise the effective stress on the soil is the confining pressure(or total stress) minus the pore water pressurewhich exists in the soil. During the shearing process, the soil sample experiences axial strain, and either volume change or development of pore water pressure occurs. How do you f...
In theoretical terms, hydraulic conductivity is a measure of how easily water can pass through soil or rock: high values indicate permeable material through which water can pass easily; low values indicate that the material is less permeable. Hydraulic conductivity is typically given the symbol k a...
adue to undrained cyclic loading of saturated sands and non-plastic silty soils has been related to frictional energy loss in the soil (Thevanayagam et al. 2002, 2003) 正在翻译,请等待...[translate] a默认语言为中文,可切换成英文 The default language is a Chinese, may cut English[translate]...
The applicability of the q_u method, which is widely used in Japan to evaluate the undrained shear strength, is examined to marine clays recovered from various sites in the world. All samples studied in this paper were collected hy the Japanese standard piston sampler. The residual effective ...
Through the process of edge erosion material is removed from the marsh edge by continuous (particle by particle) erosion, and infrequent mass failures such as slumping (Bendoni et al., 2014; Francalanci et al., 2013). Previous studies have identified a number of factors directly impacting the...
A serious problem in those analyses with the results from the direct shear tests is that the landslide motion stops upon a reduction of seismic ground motion because the residual friction angle (23°) is greater than the dipping angle of the slope (14°). On the other hand, Kuo et al. ...
Laboratories performing triaxial tests can choose from several methods. Some use consolidated soil which has been packed down, while others rely on unconsolidated soil in a sample which is as close to conditions on the site as possible. Soil can be drained or undrained for the test, depending ...
