瑶镇水库来水量分析及可供水量复核计算

Analysis on Yaozhen Reservoir inflow and water supply amount check calculation

瑶镇水库是一座以工业和城市居民生活供水为主,兼顾农业灌溉、生态用水等综合利用的中型水利工程,是解决神木县锦界工业区工业用水和城镇居民生活用水的有效工程措施。为了确定水库可供水量与初设计算结果的相差程度,对水库来水量及可供水量进行了复核。此次复核计算的多年平均径流量与瑶镇水库初步设计时计算的坝址多年平均径流量相差不大。根据瑶镇水库的长系列调节计算可知,水库多年平均可供水量为6232万m3,瑶镇水库原初步设计的供水能力为6260万m3。此次计算结果与瑶镇水库初设成果基本一致。

Yaozhen Reservoir belongs to medium water conservancy project which is based on industrial and urban citizen living water supply, which gives equal attention to agricultural irrigation, ecological water consumption and other comprehensive utilizations. It is an effective engineering measure to solve industrial water consumption and urban citizen living water consumption at Jinjie Industrial Park in Shenmu County. Reservoir inflow and water supply amount are reviewed in order to determine the difference between reservoir water supply amount and initial calculation results. The average rainfall for many yars which is reviewed and calculated is not greatly different from the average rainfall for many years in the dam site which is calculated during initial design of Yaozhen Reservoir. Long-series adjustment calculation of Yaozhen Reservoir show that the average water supply amount of reservoir for many years is 62. 32 million m3,whereas the initially designed water supply ability of 62. 6 million m3 for Yaozhen Reservoir. The calculation results this time are basically consistent with the initially design results for Yaozhen Reservoir.
