The multi-annual mean amount of runoff of Taizi River basin is about 4.6 billion m, which is the richest river in Liaohe River various branches in water volume. The flood of this basin is produced by rainstorm, the number of times is frequent, the sudden rise drops sharply, the flood peak is especially big. In addition, the coast beware of Taizi River is weakly, the amount of flood control discharge is limited. Therefore the flood along the river is severe. In order to meet the requirements including flood control, waterlogging control, industrial and urban water, irrigation water and power generation of Taizi River basin, Guanyinge reservoir would be built on Taizi River.Guanyinge hydroelectric power station project includes the design calculation of runoff regulation and water, hydro generator selection, flood regulation, dam design, hydropower plant layout, erection bays floor structure calculation.It can be known from the calcuation that the usable storage of Guanyinge reservoir is , the normal pool level is 231.66m; the selected turbine type is HL240-LJ-180, 361085.2mgenerator model is SF8-12/312; the design flood level is 234.42m, the check flood level is 235.12m; the bam is bulit up of retaining dam, overflow dam and station dam, the bam adopts energy dissipation by trajectory jet; the hydropower station plant consists of main workshop, service room, tail water channel, transformer, switch station and transportation land; the erection bays structural arrangement is beam grid, setting the level of maintenance for the rotor arc beam, there are eight pillars under the beam on the floor.Key Words：Runoff Regulation；Hydro Generator；Flood Regulation；Plant Layout；Floor Reinforcement观音阁水电站工程设计说明书- III -目 录摘 要 .IAbstract .II引 言 .11 设计原始资料 .21.1 流域概括 .21.2 气象与水文 .41.2.1 气象条件 .41.2.2 径流资料和洪水资料 .51.2.3 水库水位、库容和面积关系 .51.2.4 坝址水位流量关系 .51.3 经济、水利与功能 .101.4 坝址地质条件概述 .111.5 坝区建筑材料调查 .121.5.1 粘土料 .121.5.2 砂石料 .131.5.3 块石料 .132 径流调节和水能计算 .152.1 年径流的分析计算 .152.2 兴利调节计算 .152.3 水能计算 .
