积石峡水电站面板堆石坝湿化变形控制研究
Research on Wetting Deformation Control of CFRD for Jishixia Hydropower Station
摘要
Abstract
In the concrete faced rock-fill dam of Jishixia Hydraulic Power Station,the major material zone was filled by excavation of stones in dam area. In order to control rock-fill material’s wetting deformation,the dam bottom took immersion measures after the completion of dam filling. The monitoring results show that the dam immersion can release the wetting deformation in advance and is especially suitable for the dam body filled with the rock of smaller softening coefficient such as soft rock and weathered rock,that dam immersion can create a prerequisite condition of completion in advance and crack control from accelerating the deformation and shortening settlement time of concrete faced rock-fill dam during construction, and that the dam water level difference between inside and outside should not exceed 1 m during dam drainage stage.关键词
