摘要
应用非饱和黄土的结构性模型 ,采用考虑渗流与变形偶合作用的方法 ,编制了能够模拟非饱和黄土结构性及湿陷性的平面有限元程序 ,并对非饱和结构性黄土渠道模型离心试验进行了有限元数值模拟。有限元计算结果和模型试验结果非常接近 ,并且两者的规律性也相同 。
Based structural model of unsaturated loess and the method in which seepage and deformation is coupled, the plane FEM program which can simulate the structure and collapsibility of loess is proposed.The FEM numerical result simulating the centrifugal test of the unsaturated loess canal model is close to test result,and they have a close regularity.This result verifies that structural model of the unsaturated loess is correct and reliable.
