摘要
监控量测是隧道新奥法设计与施工中必不可少的环节。结合重庆某隧道施工支护体受力和应力监测的工程实践,分析测试结果和变化规律,阐述大跨度地下空间支护结构的开挖、量测方法及测试手段,并确定支护体的稳定性,其结果指导了该工程的信息化施工。
It is absolutely necessary of monitor measuring in design and construction using NATM. Combing with monitoring the pressure and stress of the support system in a tunnel in Chongqing City, the paper analyzes the testing results and their change law, expatiates the methods of digging, measurement and test for long span underground space support system, ascertains the stability of support system, the results directs the information-based construction in this engineering.
