| Abstract: | Based on the nonlinear hyperbolic model for load\|deformation of earth filling, the finite element analysis method for simulation the earth filling load increments in the process of construction and the interaction between soil and liner is proposed. The internal stress and earth filling pressure acting on culvert liner with extended bottom plate laid on soft foundation as well as the edge load distribution on the excavation base are determined. |

| Keywords: | culvert liner extended bottom plate earth\|fill pressure nonlinear FEM |
