摘要
格里桥水电站地处贵州高原中部高山峡谷岩溶地区,枢纽区水文地质和工程地质条件十分复杂,工程建设过程中克服了诸多难题。工程布置充分利用了工程区特点,建筑物布置紧凑,方便施工期和运行期管理。克服了狭窄场地施工布置的困难,对峡谷地区大流量泄洪问题,大坝右岸Dr2危岩体与坝体协调处理问题,大坝防渗帷幕强岩溶问题,边坡稳定及治理问题,峡谷地区碾压混凝土筑坝问题等关键技术进行了专门的研究,取得了很好的效果,确保了工程如期蓄水发电投产。
Geliqiao hydropower station ,located in karst and canyon region of Guizhou plateau ,has a rather complicated hydrogeological and geological condition in the project site .Plenty of difficulties were overcame in the construction peri-od .Considering the characteristics of the project area ,the buildings were arranged closely for the convenience of the management during construction period and operation period ,which contributed to the reasonable construction site layout in narrow field of the canyon .Meanwhile ,special studies were conducted for the following key techniques ,such as large flow discharging problem in canyon region ,coordination between Dr2 dangerous rocks and the dam body ,developed karst problem of the impervious curtain ,slope stability and treatment ,as well as damming with RCC in the canyon region . These studies achieved excellent results which would ensure that the hydropower station will operate on schedule .
