ANALYSIS BY FE VERTICAL SLICES MODEL OF A BURIED CULVERT USING DUNCAN-CHANG HYPERBOLIC SOIL MODEL
This paper introduces a new approach, referred to as the FE vertical slices model, which is specifically designed to study the response of a box culvert under distributed load acting on the soils surface. The applied finite element procedure treats the culvert and its surrounding soil as a pseudo three-dimensional medium, which is divided into vertical slices. Each of these slices is considered as a plane stress problem, with the soil obeying the nonlinear hyperbolic model. To validate the effectiveness of this method, a comparative analysis is conducted with other numerical methods. A limited parametric investigation is carried out to assess how the dimensions of the box culvert and its embedment influence the distribution of vertical pressures.
