Land subsidence results from changes in the pressure borne by pore water in the soil and the effective stress borne by soil skeleton.
地面沉降是土层中孔隙水承担的孔隙水压力和土骨架承担的有效应力发生变化的结果。
In this paper, the saturated soil is dealt with as a two phase media. Thefric 'ion between the soil skeleton and porous liquid is considered.
将饱和土作为二相介质，考虑土骨架和孔隙流体之间的摩阻力，建立了饱和土中一维压缩波传播的二相动力分析控制微分方程，采用有限差分法求解。
If the soil skeleton is regarded as the viscoelastic media, the stress-strain relation will be changed with time, which increases the complexity of the problems.
当土骨架是粘-弹性介质时，应力与应变的关系随时间变化，增加了问题的复杂性。
