The Analysis on Effect of the Terrain to the Culverts Stress by the Finite Element Method

Highlight advantages of the finite element method is suitable for non-linear, non-homogeneous, complex boundary conditions. The paper adopts the finite element method to analysis culvert stress in Valley terrain. Gain that when the filling height H=40 meters, considering the valley topography calculated Ks=1.19, otherwise the Ks=1.435, the difference is about 17%. Therefore, the effects of the valley terrain to the high embankment culvert can not be ignored.
