摘要
软土地区的深基坑工程除了保证基坑本身的安全和稳定外,更重要的是保护邻近建筑物以及地下管线等市政基础设施的安全。文章以某明挖隧道基坑群为例,分析了基坑开挖和降水对高压燃气管线的影响,得到了高压燃气管线在基坑开挖和降水过程中的位移变化规律,可用于指导工程实施,对类似工程有一定的借鉴意义。
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.
