Development of Finite Element Model Technology for Composite Pipe with Sewage Pipe Renewal Method


The aim of this study is to evaluate the behaviour of buried pipes utilizing the Sewage Pipe Renewal (SPR) method through a finite element analysis. A finite element program, ABAQUS, will be used for the static analysis of the pipes. Maximum stresses and displacements are tabulated and plotted into graphs for the analysis. Varying lengths, materials, bedding angles, boundary conditions are considered. Lengths of 1m, 3m, 5m, and 10m meters are used, but only the 3 and 5 meter pipes are used for the modelling of pipes with various bedding angles and boundary conditions. Two sets of boundary conditions are used in this study to represent the bedding support on the pipe. A fixed boundary condition and a series of soil springs are used to model the bedding support of the pipes. Based on the FEM results, length of the pipes is not a factor for the magnitude of maximum stresses and deflections of buried pipes. However, increasing bedding angles of the buried pipes decreases the value of stresses and displacements. Additionally, pipes with soil springs applied as bedding support increases the stress and displacement remarkably. Analyses and concluding remarks are provided at the end of this study
