摘　　要：白鹤滩水电站左岸导流隧洞混凝土施工具有衬砌断面大、工期紧张、混凝土浇筑强度高、温控要求高、裂缝防控难度大等特点。同时,受白鹤滩地区风速大、夏季气候高温、多雨等环境影响,如何保证导流隧洞混凝土在衬砌施工过程中的质量控制就变得尤为重要。因此,在浇筑混凝土前,应结合白鹤滩地区的实际情况对混凝土的各项指标进行确定、合理布局、统筹兼顾,进而为导流隧洞混凝土衬砌施工提供合适的质量管控措施及标准。Concrete construction of diversion tunnel in left bank of Baihetan hydropower station is characterized with large lining section,urgent construction period,high concrete placement rate,strict temperature control requirements,difficult crack prevention.At the same time,the project is influenced by high wind speed,high temperature and much rainfall in Baihetan area,so it is very important to ensure construction quality control during concrete lining of the diversion tunnel.Therefore,before concrete placement,the each index should be determined according to actual conditions in Baihetan area,then rational layout and overall considerations should be given to provide proper quality control measures and standards for concrete lining construction of diversion tunnel.
