摘要/Abstract

摘要： 简单介绍了锦屏一级水电站左岸导流洞的工程地质概况及施工期安全监测设计，详细阐述了施工期安全监测成果，对围岩的变形、应力规律及特征进行了深入的分析。目前该导流洞开挖支护已完成,围岩变形及锚杆应力变化较小，表明围岩已趋于稳定。安全监测为设计与施工提供了可靠的依据。

Abstract: This paper introduces geology status and safety monit oring design of the left diversion tunnel in construction of Jinping - 1 Hydropower Project simply, expatiates on the results of safety monitoring in construction, and analyzes the rules and characters of stress and deformation of surrounding rock. Now the diversion tunnel has been completed, the changes of deformation and anchor stress for surrounding rock are small. This result shows that the surrounding rock is stable, safety monitoring result can provide reliable basis for design and construction.
