摘要
对某水电站左岸1#、2#导流洞施工期进行安全监测,通过获取的大量施工期监测数据及成果,分析、总结了施工对于围岩稳定和支护结构的影响规律及特征,分析表明围岩已趋于稳定。安全监测较好地指导了现场施工组织,保证了施工工作的顺利开展,也为后续类似工程的施工总结了宝贵经验。
The security monitoring of division tunnel 1 ^# and 2^# of hydropower station during construction is studied, in which amount of monitoring data and results are obtained. It shows that the adjacent rock is stable by analysis of influence and charac- teristics of stability of adjacent rock and support structure during construction. The construction management is guided by security monitoring, which is provided as experiences for similar engineering＇s construction.
