长引水隧洞安全监测设计关键技术初探

Key technology of safety monitoring of long diversion tunnel

以某水电站长引水隧洞为依托,对施工期围岩变形、永久围岩变形和锚固应力等,以及跨沟明管段衬砌钢筋应力进行监测设计,从而针对长引水隧洞监测设计关键技术进行初步探讨。

Based on a long diversion tunnel of a hydropower station, the paper discusses the monitoring design for cofferdam deformation during construction period, permanent cofferdam deformation and rock bolt stress, and stress on the lining steel bars of the gullycrossing open pipe. Some key technology for monitoring long diversion tunnels is proposed, which provides a valuable reference for similar projects.
