车站深基坑施工对原水管变形影响的监测分析

Monitoring and Analysis of the Impact of Deep Foundation Pit Construction at a Station on the Deformation of Raw Water Pipes

大型原水管作为城市供水重要的生命线,其运营安全事关千家万户的生活。文章以所建地铁车站深基坑施工工程为例,结合临近原水管自身竖向位移及周围土体深层水平位移布设情况,针对不同施工工况中原水管竖向位移及土体深层水平位移成因监测数据进行分析,提出了有效控制周边土体及原水管自身变形的技术措施。本文内容可为类似深基坑施工过程中对原水管的监控保护提供借鉴,以确保原水管安全运营。

As large-scale raw water pipes are a vital lifeline for urban water supply,their operational safety is crucial for the well-being of numerous households.This paper takes the deep foundation pit construction project of a subway station as an example.By integrating the monitoring data of the vertical displacement of the nearby raw water pipes and the deep horizontal displacement of the surrounding soil under different construction conditions,the paper analyzes the causes of these displacements.It proposes technical measures to effectively control the deformation of the surrounding soil and the water pipes themselves.The content of this paper can serve as a reference for the monitoring and protection of raw water pipes during similar deep foundation pit construction processes,ensuring the safe operation of these pipes.
