In addition to ensuring the safety and stability of the foundation pit itself,the deep excavation project in soft soil areas is more important in protecting the safety of nearby buildings and municipal infrastructure such as underground pipelines.This article takes a group of open cut tunnel foundation pits as an example to analyze the impact of foundation pit excavation and precipitation on high-pressure gas pipelines.The displacement variation law of high-pressure gas pipelines during foundation pit excavation and precipitation is obtained,which can be used to guide engineering implementation and has certain reference significance for similar projects.
