Abstract: Aiming at the problem that the soil is easy to be disturbed when expanding in saturated soft soil, the disturbance coefficient is introduced to describe the degree of disturbance. In the plastic zone, the yield criteria of soil at different positions are given by linear interpolation, and the stress distribution in the expansion process is deduced based on the undrained condition. The distribution law of excess pore water pressure after expansion is given by using Henkel pore water pressure theo... More
