With the rapid development of the economy, construction has been carried out throughout the country. Natural gas pipe network is widely distributed, so construction vehicles driving on the ground with buried gas pipelines often exert pressure on the pipelines. If the pipelines are not buried deep enough, the pipeline material strength is poor or the construction quality is not qualified, the pipelines may be deformed or even broken when they are under high pressure. In this paper, the influence of excavator and heavy truck load on gas pipeline is analyzed by using finite element software. The results show that the construction vehicle propagates pressure load through the soil, which causes the local concentrated pressure above the pipeline and causes the pipeline deformation. In view of the safety hidden danger caused by the third party construction vehicles, this paper also gives some Suggestions and measures.
