Document Type: Proceeding Paper

Part of: Pipeline Design and Installation


The deformation of flexible culverts is analysed using the finite element method as tool. Results of calculations for installation, traffic and time dependent loads are presented for culverts in homogeneous sand and in layered soft soil embedded in a granular fill and compared with deformation measurements. Finally the ultimate bearing capacity of a culvert under homogeneous conditions and in layered soft soil are compared and the failure mechanisms analysed.
