高山峡谷区水利工程泵站取水方案浅析

Analysis on Water Intake Scheme of Hydraulic Engineering Pumping Station in High Mountain and Gorge Area

针对山区高扬程、长距离输水工程,因受征地、移民、压矿、生态环境、地质条件等影响,挡水大坝址往往地处高山峡谷区,左右岸地形一般较陡,对外交通条件较差,对泵站的选型和取水方案设计带来了较大的挑战。文章以某中型水利工程为例,主要探讨高山峡谷地区中水利工程泵站不同取水方案,在技术可行、安全可靠前提下,以财务指标最优确定最优方案。

Due to the influence of land expropriation,migration,mining pressure,ecological environment,geological conditions,etc.,the dam site of water retaining is usually located in the mountain valley,and the terrain on the left and right banks is generally steep and the external traffic condition is poor,which brings great challenges to the selection of pumping stations and the design of water intake schemes.Taking a medium-sized hydraulic engineering as an example,the different water intake schemes of hydraulic engineering pumping station in the high mountain and gorge area are mainly discussed in this paper.Under the premise of technical feasibility,safety and reliability,the optimal scheme is determined by the optimal financial index.
