摘　　要：由于隧洞工程的特殊性、复杂性和隧洞围岩的不确定性,对隧洞围岩及支护结构等结构进行监控量测是保证隧洞工程质量、安全的必不可少的手段。向家坝尾水隧洞施工具有跨度大、断面大,施工干扰大等特点。介绍了向家坝水电站尾水隧洞施工期的监测方法,并对其监测数据进行分析,可供类似工程参考。Due to the particularity of tunnel projects, and the complexity and uncertainty of tunnel surrounding rocks, the monitoring measurement of the structure of tunnel surrounding rocks and the supporting structure is the indispensable means to assure the quality and safety of tunnel projects. The construction of tailrace tunnels in Xiangjiaba has the characteristics of large spans, large section and large construction disturbance. The monitoring method of tailrace tunnels during construction is described, and its monitoring data are analyzed. The example is available for reference to similar projects.
