考虑液化后饱和砂土在重新固结时砂土骨架的压缩变形 ,对冲击造成液化的饱和砂土在排水与密实过程中砂面沉降速度、沉降量、超孔隙水压力等参数随时间的变化进行了初步的分析。在对液化后饱和砂土的渗透系数进行必要的修正后 ,分析计算结果与实验结果吻合得较好
Taking into account the compressive deformation of the sand matrix after reliquefaction of the liquefied saturated sand, the sedimentation velocity, settlement and excess pore water pressure of the liquefied saturated sand during drainage and densification change with time Conducted a preliminary analysis. After the necessary correction to the permeability coefficient of saturated sand after liquefaction, the calculated results agree well with the experimental results
