1、毕业论文摘要河流上修筑水工建筑物，关系着下游千百万人民生命财产安全。本设计主要论述了柳村水电站施工导流、导流建筑物的形式、围堰的结构设计及稳定分析、混凝土施工等。柳村电站枢纽位于西藏昌都地区左贡县境内怒江一级支流玉曲河上，为无调节坝后式小型水电站。该电站由拦河坝、泄洪建筑物、引水建筑物及电站厂房组成。电站设计装机容量为2×800kW，施工总工期2年。本枢纽导流建筑物为V级，电站施工导流设计流量采用平水年平均径流流量Q=49.36m3/s在导流方案设计时，分别采取了全段围堰法和分段围堰共6种方案的论述，经过技术和经济论证，最终采用分段
2、围堰法施工。围堰材料采用草土袋，土工布防渗，经过抗滑稳定的分析，围堰符合设计标准。混凝土施工组织设计包括混凝土的配制，混凝土的浇筑，混凝土的温度控制，混凝土的养护，钢筋及模板作业等。柳村电站枢纽为浆砌石硬壳坝,混凝土施工主要在电站厂房坝段、溢流面、上游面板及下游消能池。关键词：施工导流，全段围堰法，分段围堰法，混凝土施工第II页共56页毕业论文AbstractBuildthewaterconservancyprojectbuildingontheriver,isconcerningagreatamountofpeople'ssafe
