摘要:

围岩变形特性综合反映了开挖引起围岩形态的变化,是判断地下工程稳定状态最直观的依据,因此新奥法的实施贯穿了变形监测和监测资料的反馈分析。结合一定的工程背景,探讨了在复杂地质条件下修建大跨度双连拱隧道中监控量测技术的运用,并总结出一定的经验,供类似工程借鉴。

Abstract:

The property of the deformations of the surrounding rock mass comprehensively reflects the changes of the rock mass caused by excavation and is the most direct evidence to judge the stability of the underground works. Therefore, monitoring and measurement, as well as feedback and analysis of the monitoring results, are always conducted during the complete process of the NATM construction. On basis of an engineering case, the article makes discussions on the application of the monitoring and measurement technology in the construction of largespanned double-arched tunnels under complex geological conditions and summarizes some successful experience, which can provide reference for similar works.
