Excess pore water pressure ratioThe excess pore water pressure (EPWP) ratio is one of the contributing factors to the earthquake-induced uplift displacement of underground structures. To investigate its role in the incompletely liquefied soil, a rectangular underground structure buried at different ...
This type of soil response is similar conceptually to that induced by earthquakes due to the build-up of the excess pore pressure. The generated pore pressure is dependent on the substrate's relative density, induced cyclic shear stress ratio and pre-existing pore pressure. In the case of the...
In all these tests, the change in excess pore water pressure was measured around the pile at two spots: at the middle of the pile and at its tip. The results revealed that the generation of excess pore water pressure was affected by the following parameters: slenderness ratio of the pile,...
aIn a consolidated undrained triaxial test, the tendency of the dense sand (under stress ratio of tls' > sin cv) to dilate results in a decrease in the generated excess pore-water pressure and in an increase in the sand resistance to the applied deviatoric stress. 在一个巩固的undrained三轴...
pore water pressure; at the same void ratio, the steady state strength of saturated loess is not affected by early stress path, but related to ... X Zhang,X Pei,J Jia,... - 《Journal of Geomechanics》 被引量: 0发表: 2018年 加载更多来源...
Consequently, the liquefaction resistance of saturated sand was cleared to be affected by three factors, pre-shear strain (effective shear stress ratio), excess pore-water pressure (effective stress condition) at preshearing, and the number of cycles. And the increase of liquefaction resistance was...
The grain size composition and structural strength dominate the excess pore pressure response. The wave-induced liquefied depth of intact seabed sediment is significantly affected by the initial physical properties such as dry density, void ratio, saturation degree, etc. To a large extent, the ...
Randolph and Wroth (1979) evaluated this consolidation time from the cavity expansion method based on initial excess pore pressure and the rigidity index (a ratio of shear modulus and undrained shear strength (Ir=G/su)) for piles driven in clay where the value Ir ranges from 50 to 500. ...
4) excess pore pressure 超孔隙水压力 1. On the other hand,under the drawdown condition of the reservoir,the excess pore pressure will be produced for the sake of the lagged effect of the declining underground water. 水库蓄水后,将形成大量的涉水岸坡,当水位上升时,坡体中由于水的渗入,导致坡...
