Abstract: To analyze the effect of impact load on the safe operation of buried polyethylene gas pipelines near the impact loading zone, a finite element analysis software ABAQUS was used to analyze the stress variation of polyethylene pipe with the pipe-soil interaction finite element model. The variation of stress and deformation was analyzed with different polyethylene pipe material models, soil properties and impact velocity. The results indicated that the impact velocity of polyethylene pipeline did not show any change due to the impact with relatively short time. There was a significant protective effect on the pipeline from the soil properties and reasonable burying depth. The polyethylene pipeline exhibited an increase in maximum stress with an increase of internal pressure of the pipe, which has an approximately linear relationship. The area near the impact zone was found to reach a failure limit easily for polyethylene pipe.
