Abstract

Consolidation and drainage tests were carried out for undisturbed saturated soil with a buried depth of 70~100m in Fuyang region. Automatic triaxial apparatus was used for tests as it can provide big confining pressure, and solve the problem of seepage along side wall, which happens with varying water head permeameter. Test results show that with continuous increase of confining pressure, water volume discharged due to consolidation of deep saturated clay is not equal to soil volume compressed. Expansion effect of soil volume takes place. And permeability of soil decreases as an exponential function with the increase of confining pressure. Stabilization of soil permeability generates time-lag effect. The test results will affect simulation of ground settlement with regard to water volume supplied by released water due to consolidation of clay in confined aquifer for shallow aquifer.
