1 概述南阳回龙抽水蓄能电站位于南阳市南召县城东北约16km的岳庄村附近,是为解决电力调峰问题而专设的调峰电站。工程主要包括上库主、付坝、下库大坝、引水发电系统、地下厂房、辅助开关站等主要建筑物。电站装机容量2×60MW,上库总库容113万 m~3,下库总库容129万 m~3,引水洞线总长1834m,最大静水头461m,动水头568m。本项目研究内容、目的及意义为:是为回龙抽水蓄能电站上库库盆防渗设计方案提供科学的分析方法和决策依据。同时,形成一套全新、系统、完善、全面、便捷的裂隙岩体三维渗流分析方法、模型及软件,以期推广应用于所有水利水电工程。收集大量国内外有关库盆防渗衬砌的型式,开发新的防渗材料,
1 Overview Nanyang Huilong Pumped Storage Power Station is located near Yuezhuang Village, about 16km north-east of Nanzhao County, Nanyang City. It is a peaking power station specially designed to solve the problem of power peaking. The project mainly includes the main library, the pay dam, the reservoir dam, diversion power generation system, underground powerhouse, auxiliary switchgear and other major buildings. The installed capacity of the power station is 2 × 60MW, the total storage capacity of the upper reservoir is 1,130,000 m 3, the total storage capacity of the lower reservoir is 1,2,900 m 3, the total length of the diversion tunnel is 1834m, the maximum static water head is 461m and the movable water head is 568m. The research content, purpose and significance of this project are as follows: It provides a scientific analysis method and decision-making basis for the seepage prevention design scheme of the upper reservoir of the Huilong Pumped Storage Power Station. At the same time, a set of new, systematic, complete, comprehensive and convenient three-dimensional seepage flow analysis methods, models and softwares for fractured rock mass are formed, so as to be widely applied to all water conservancy and hydropower projects. Collection of a large number of domestic and international basin basin impervious lining type, the development of new impermeable materials,
