管道工程穿越既有轨道交通安全评估与监测实例分析

Case Analysis of Safety Assessment and Monitoring of Existing Rail Transit in Pipeline Engineering

由于管道工程临近地铁保护区的项目不断增加,安全评估和专项监测的应用非常必要。论文以某出水管工程涉及轨道交通5号线为例,设计了专项监测方案,重点分析了管道施工影响既有地铁车站结构安全评估预测与实测的监测变形,验证了安全评估的预测值与实际监测数据的符合性。

Due to the increasing number of pipeline projects near metro protected areas,the application of safety assessment and special monitoring is very necessary.Taking a water pipe project involving rail transit Line 5 as an example,this paper designs a special monitoring scheme,focuses on analyzing the monitoring deformation of existing subway station structure affected by pipeline construction,verifies the conformity of the predicted value of safety assessment with the actual monitoring data.
