金沟河流域水利枢纽坝址方案比选分析

Scheme Comparison and Selection Analysis of Dam Site of the Jingou River Basin Water Conservancy Project

文章根据金沟河流域水利枢纽坝址区地质条件,提出上、下坝址两个比选方案,从地形地质条件、枢纽布置、施工条件、运行管理条件、工程投资等方面对两个坝址进行综合技术经济比较,结果表明,上、下坝址相距较近,地质条件基本相同,上下坝址均具备建坝条件,但下坝址具有枢纽布置相对合理、投资较省的优点,比选方案可为类似工程提供参考。

According to the geological conditions of the dam site area of the Jinguou River Basin Water Conservancy Project,two comparison schemes of the upper and lower dam sites are put forward in this paper.A comprehensive technical and economic comparison of the two dam sites is made from the aspects of topographic and geological conditions,key layout,construction conditions,operation and management conditions,engineering investment,etc.The results show that the upper and lower dam sites are close to each other,and the geological conditions are basically the same.Both the upper and lower dam sites have the conditions for dam construction.However,the lower dam site has the advantages of relatively reasonable layout of key points and low investment.The comparison scheme can provide reference for similar projects.
