| 摘 要： | 土体中大量降排水的过程实际上是土体中有效应力增长的过程。通过对抽水试验中土体渗透系数的回归分析,建立了渗透系数与有效应力增量之间的耦合响应模型关系,说明降排水过程中土体渗透系数是呈非线性变化的。

| Abstract: | The process of pore water discharge in soils is actually a process of effective stress increase.Through regression analyses of permeable coefficients in soils during the pumping test,nonlinear coupling response relationship is established between permeability coefficients and effective stress increase.It is concluded that the nonlinear variation of permeable coefficients of soils in the course of water discharge. |
