水布垭水利枢纽工程施工规划

Construction plan of Shuibuya hydroproject

水布垭水利枢纽混凝土面板堆石坝为世界同类坝型的第一高坝,地下电站系统等地下工程规模位于国内水电工程前列。坝址河谷狭窄,地形陡峻,坝址下游地形稍缓,但分布较多滑坡体;坝址上部岩体为灰岩,岩溶发育,下部为泥页岩,总体呈上硬下软分布,地质条件复杂。为保证工程的有序、高效、安全实施,在工程建设前期制订了科学、合理的施工规划,在工程建设过程中严格按施工规划组织施工,保证了工程建设目标的实现。从施工导流、施工进度、场内交通、施工布置等方面,简要介绍了水布垭工程的施工规划,以供其它工程参考。

The concrete faced rockfill dam of Shuibuya hydropower station is the highest dam in the similar type in the world,and the scale of its underground power station ranks forefront in home.The river valley at dam site is narrow,the geography is steep;the downstream geography of the dam site is gentle,but many landslides distributes;the upper rock mass of the dam site is limestone with developed karst,the lower rock is clay shale,in general,the upper part is hard and the lower part is soft,and the geological condition is complicated.In order to guarantee order,efficient and safe construction,a scientific and reasonable construction plan was made before construction and strictly implemented in construction,and the construction goal was realized.From construction diversion,construction progress,construction traffic,construction layout etc.,this paper briefly introduces the construction plan for reference by other projects.
