黄金峡水利枢纽泵站、电站联合布置方案研究

Research on Joint Layout Scheme of Pumping Station and Power Station of Huangjinxia Hydro-Junction

黄金峡水利枢纽是引汉济渭工程的第一水源地,包括大坝、泄水、电站、泵站及通航建筑物,协调布置水工建筑物尤其是电站、泵站的布置是工程设计的重点和难点。对3个方案分别从进水布置及条件、厂房布置、交通及施工条件、出线等进行技术、经济比较,最终推荐了河床式泵站与坝后式电站联合布置的型式。工程布置充分利用了泵站与电站机组安装高程的高差,统筹布置两个建筑物进水口,进厂道路协调分层关系,出线平台采用两站共用,施工、交通、导流等临时设施布置与枢纽大坝统一考虑。通过联合布置设计,枢纽工程布置紧凑、简洁,工程占地少,减少了开挖量,空间布局合理,节约了投资,有利于工程集中运行管理,具有可行性。

The ultimately recommended arrangement of the pump station and power station of Huangjinxia Hydro-Junction which had gone through various schemes was the first of its kind in our country. The layout made good use of the height difference between the installation elevation of the pump station and power station as well as the width of the inlet, which could serve as a highly profitable practice. The compact and concise layout of the project occupied less land, thus greatly reducing the amount of excavation. Meanwhile, the centralized engineering management was also of high feasibility.
