Numerical Simulation and Earth Pressure Analysis of Backfilling in Layers for High Embankment Culvert

Lin Shuo-ping

Abstract

The process of culvert soil backfilling in layers was numerically simulated by the life-and-death unit of analysis software of FEM(ANSYS).Then,the distribution law of the vertical earth pressure on the egg-shaped arch culvert and the trunk culvert was analyzed.The concentration factor of numerical simulation was compared with the whole calculation.The real test result of egg-shaped arch culvert stress indicates that the calculation result of numerical simulation better conforms to engineering reality.
