Abstract
At present, the rolling load of heavy vehicles has become one of the main ground loads threatening the safety of buried pipelines. In this paper, the vehicle simulation is carried out based on ADAMS to extract the wheel force. At the same time, the pipeline soil coupling model is established based on ABAQUS. The amplitude of the random moving load extracted by ADAMS is used for finite element simulation calculation, the dynamic response process of the pipeline is simulated, and the stress distribution of the buried pipeline under the vehicle rolling load is obtained. Aiming at the pipeline stress concentration area, that is, the most vulnerable area of the pipeline, the pipeline load reduction and prevention and control measures are proposed, and the four measures are compared, which provides theoretical support for the actual engineering prevention and control.
