A Numeric Analyses Method and Application of Loess Collapse Deformation

Article Preview

Abstract:

The collapse settlement of loess foundation is one of issues in engineering which need to be solved. Firstly, a finite element program was developed and the computational function of collapse deformation was implemented based on chord modulus method. Then, the comparison of the measured collapse settlement in a loading plate test and the computational collapse settlement based on the finite element were analyzed. The computational results show that the nonlinear finite element method based on the chord modulus should be recommended to evaluate the collapse deformation, owing to its potential application that it may consider the collapse deformation field of the whole collapsible loess foundation.
