摘要
本文以某大型市政管网改造施工对地下已运营、在建地铁安全评估为背景,采用FLAC计算软件分析管线基坑开挖、顶管施工对地铁隧道的影响,对比变形数据、监测数据并提出相应建议。分析结果表明:DN1200mm的大直径管线顶管施工对既有地铁隧道产生的水平位移和竖向位移最大值均满足控制标准,可为今后类似工程项目提供参考。
Based on the safety assessment of a large-scale municipal pipeline renovation project on the subways both in operation and under construction,FLAC calculation software is used to analyze the impact of foundation pit excavation,pipe jacking construction on subway tunnels,so as to compare deformation data and monitoring data,as well as put forward corresponding suggestions.The results show the maximum horizontal displacement and vertical displacement generated by the pipe jacking construction of DN1200mm large-diameter pipeline in the existing subway tunnels meet the control standards,which can provide reference for similar projects in the future.
