监控量测在陕鄂界隧道施工中的应用

The application of monitoring measurement in tunnel construction of Shaanxi-Hubei boundary

以陕鄂界隧道工程为例,详细介绍了特长隧道监控量测方法之一周边位移和拱顶下沉的测量方法和原则,通过对实际量测数据进行分析,使得围岩支护参数的调整有了可靠的依据,为今后同类条件下的隧道施工提供了宝贵经验。

Taking the Shaanxi-Hubei boundary tunnel project for example, this paper introduced one of monitoring measurement methods of extra-long tunnel in detail the measurement methods and principles of surrounding displacement and vault settlement, through the analysis on actual measurement data, made the adjustment of surrounding rock support parameters have reliable basis, provided valuable experience for similar conditions tunnel construction in future.
