地铁隧道施工监控量测与分析

Monitoring Measurement and Analysis of Subway Tunnel Construction

随着我国城市交通建设快速发展,地铁隧道数量不断增加,隧道施工遇到的不良地质问题越来越多.监控量测作为保障安全、优化设计、指导施工的重要手段,其技术的进步对不良地质隧道施工具有重要意义.笔者结合深圳地铁3号线横岗车辆段隧道监控实践,分析了施工监控数据反馈施工,总结出了地铁隧道监控应注意的事项,对类似工程具有参考意义.

with the rapid development of urban transportation construction, there is an increase in the number of subway tunnel;meanwhile, more and more unfavorable engineering geological problems appear during tunnel construction. Monitoring measurement, as one significant means to ensure security,opti mize design, guide construction, its technological progress exerts a vital influence on unfavorable geology＇ stunnel construction. Considering the practice of tunnel monitoring in Henggang depot of No. 3 subway Shenzhen,this article analyzes construction monitoring data which will be fed back to construc tion,and summarizes the precautions that need to be paid attention in the monitoring of subway tunnel, all of which plays a reference effect in other similar projects.
