Abstract

Abstract

The K0 loading-unloading tests for sand, saturated silt and silty clay were conducted, using the JCY consolidation apparatus, then the v-h relationships during the tests were described by K0 loading-unloading model.The parameters of K0 loading-unloading model were discussed. Several results were concluded. The v-h relationship is linear during loading, and it is unlinear during unloading. When the vertical stress v equals to zero during unloading, the residual horizontal stress is affected by the viscosity of the soil. The v-h relationship during K0 loading-unloading can be calculated by K0 loading-unloading model. The parameters K0(NC) and are affected by the friction angle .
- K0 loading-unloading,
- horizontal stress,
- coefficient of earth pressure at rest
