越南永河水电站工程枢纽布置设计

General Layout Design of Vietnam Vinhha Hydropower Station

根据地形地质条件,对越南永河水电站工程上、中、下坝址进行综合比选,确立推荐坝址,并介绍了电站枢纽建筑物布置设计的原则和过程。通过综合比选和设计,越南永河水电站工程从左至右枢纽布置为左岸重力坝、厂房安装间段、厂房主机间段、泄水闸坝段、右岸闸检室坝段及右岸接头重力坝段。该方案技术可行,经济较优,已通过越南电力主管部门及业主审查,项目已经进入施工图阶段。

According to the topographical and geological conditions, the upper, mid and lower dam sites of Vietnam Vinhha Hydropower Station are comprehensively compared and selected, so as to determine the recommended dam site. Meanwhile, design principle and process of general layout of hydro-complex buildings are discussedin this paper. Through comprehensive comparison and selection, the hydro-complex layout from left to right isleft-bank gravity dam, powerhouse erection bay section, powerhouse generator hall section, discharge sluice damsection, right-bank gate maintenance chamber dam section, and right-bank joint gravity dam in turn. Thisscheme has advantages in feasible technology and favorable economy, which has been reviewed and approved bythe Employer and Electric Power Administrative Department of Vietnam. So, the detailed design works of thisproject have been carried out.
