영문 초록

Sewage Pipe Renewal (SPR) method rehabilitate pipeline by forming a PVC profile inside the pipe by using a winding machine without excavating the soil above the pipe which lowers the cost of the rehabilitation. This study will investigate the effects of varying the pipe's diameter to its wall thickness ratio. The dimensions for the diameter and minimum wall thickness of the non-reinforced concrete pipe will be based from ASTM C14. The finite element analysis software, ABAQUS, will be used to model and perform the analysis for the composite pipes. To account for the soil-pipe interaction, soil springs will be used as the bedding support to hold the pipe in place. Additionally, three soil types will be used to compare the behavior of the pipe with different diameter to thickness ratios. The results from the finite element analysis will be shown in tables and plotted into graphs and a concluding remarks will be provided.
