High Embankment Culvert Culvert Vertical Earth Pressure And Settlement Deformation Finite Element Method,

This paper analyses the performance of the stress and deformation of the culvert under the embankment of high-stacked soil through the programs of PATRAN and MARC. The author sets up the calculating moulds of plane and three-dimension and select the M-C yield criterion, and draws the change laws of the concentration coefficient of the vertical soil pressure of the culvert top with the height of the stacked soil and the settlement of the culvert bottom with the height of the stacked soil. The author also analyses the effect of the terrain conditions of the culvert construction on the concentration coefficient and the settlement of the culvert bottom. Finally, the calculating results are analyzed by connection to concrete engineering.
