The FEM analysis on centrifugal model test of inundation deformation of structural loess canal

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.
