水布垭枢纽总体布置研究

水布垭水电站工程坝址地形和地质条件复杂，建筑物规模巨大，坝高达２３０ｍ左右。根据坝址自然条件和其它条件，在可行性研究中主要考虑了两种坝型：混凝土板堆石坝和土料心墙堆石坝。针对这两种坝型进行了枢纽布置研究。

Project layout of Shuibuya Hydropower Station

The feasibility study for Shuibuya Hydropower Station is being conducted. The topographic and geologic conditions at the project damsite are complicated, and the sizes of its structures are quite large, with the planned maximum dam height of 234 m. According to the natural conditions at the damsite and other relevant situation, two kinds of dam type have been considered, i.e. the concrete faced rockfill dam and the rockfill dam with soil core. For these two dam types, studies on the project layout have been carried out. In this paper, the topographic and geologic conditions at the damsite, the principle of the projcet layout, the arrangement schemes of the concrete faced rockfill dam and the rockfill dam with soil core, and the advantages and disadvantages of each scheme are presented in detail.
