Centrifuge modeling of one-step outflow tests were carried out using a 2-m radius geotechnical centrifuge, and the cumulative outflow and transient pore water pressure were measured during the tests at multiple gravity levels. Based on the scaling laws of centrifuge modeling, the measurements generally showed reasonable agreement with prototype data calculated from forward simulations with inpu...

The pore-water pressure is a vital factor in determining the slope stability. To deal with stability of slopes undergoing pressures, this paper used coefficient to develop three-dimensional limit analysis method for evaluation nonlinear strength envelope. For numerical examples, critical heights and corresponding slip surfaces associated linear envelopes were derived by using optimization proce...

Activated carbons fibers (ACFs) possess considerably uniform slit-shaped micropores of great pore volume. Molecules are strongly adsorbed in the micropores of the deep molecular potential well which stems from the overlapping of the molecule-pore wall interaction from opposite pore walls. Thus, a substantial adsorption of vapor begins at a very low-pressure region, giving rise to a monolayer ad...

Excess pore pressure under seismic loadings has always been a main concern in geotechnical engineering practices. The phenomenon in soil can cause an effective stress and hence cause the shear strength of the soil to decrease considerably and large deformations to occur in the area. Generally, increases in pore pressure occur in un-drained conditions. If it is formed, its consequences decrease ...
