Influence of Culvert Structure Style and Boundary on Vertical Earth Pressure Distribution of High-Filled Culvert

Abstract:

The actual stress state of high filled culvert was not accurately reflected by the calculation method of earth pressure in the prevailing Chinese General Code for Design of Highway Bridges and Culverts. So the vertical earth pressure characteristics of different culvert structural style under fill-load were studied based on field temperature and FEM numerical analysis. Meanwhile, the key influencing factors, such as the height of culvert fill, and boundary condition on the earth pressure characteristics were also discussed. It is shown that the distributions of vertical earth pressure on the middle culvert top and culvert flank wall, as well as culvert side are all nonlinear, they are different from the results calculated by the code method under the high fill load. The influence of the factors on the stress state of high filled culvert should be comprehensively considered. The results can give some references on the design and construction procedure.
