ANSYS Finite Element Analysis of Widened Settlement Law Based on Existing Road

Through analysis of actual studing the differential settlement of widened road,the shortages of present calculate method are indicated.Integrating with general purpose finite program ANSYS,viscoelastic materials are chosen to simulate the non-linearity of soil.The finite element analysis of widened road is given,the law of differential settlement summarized and the suggestions for the design of widened road are put forward based on the computed results.
