Numerical Simulation Comparative Analysis of Pipe Soil Interaction in Buried Pipeline

Aiming at the problem that there is no effective tool to quickly analyze the mechanical response of long-distance buried pipelines, this paper uses the APDL language of ANSYS to compile a rapid solution program for the mechanical response of buried pipelines based on the soil spring model. The program is used to establish the calculation model of 500 m long pipe, and analyze the mechanical response of the pipeline with and without medium and subsidence. The value are compared with those of ABAQUS based on PSI unit and solid contact model. The results show that the calculation value of these three methods are in good agreement. The program can realize rapid modeling and accurate analysis of long-distance buried pipelines, and has high engineering application value.
