摘要
介绍了吉牛水电站安全监测的布置设计,对施工期、大坝蓄水期、在建世界上最长的引水隧洞及507 m高水头压力管道充水期的监测成果进行了分析。分析结果表明:布置于大坝、引水系统、地面厂房中的各项监测仪器在施工期运行正常,监测数据准确、合理;大坝蓄水后其变形、渗流渗压监测结果满足设计要求;引水隧洞及压力管道充水后的变形、应力、渗流监测结果满足设计要求。监测结果表明:各建筑物投运后运行性态稳定。
In this paper,layout design of safety monitoring for Jiniu hydropower station is presented,monitoring results during construction,reservoir impoundment,water filling periods for the longest headrace tunnel under construction in the world and 507m high head penstock are analyzed. The analysis results indicate that the various monitoring instruments placed in dam,headrace tunnel system,surface powerhouse are working normally and the monitoring data are accurate and reasonable; After reservoir impoundment,the deformation and seepage flow and pressure monitoring values meet design requirements; After water filling of headrace tunnel and penstock,the deformation,stress and seepage flow monitoring values meet design requirements.The observation show that operation conditions are stable for various structures after operation.
