摘要
以苗尾水电站为例,研究了截流过程中下游不同水位运用方式对导流洞水位流量的影响。试验表明,下游水位高,会影响导流洞进口水位和出流状况,并且龙口流速和单宽功率较低。并且水位越高,对导截流的影响越大。
Based on the Miaowei Hydropower Station,this paper studies the impact of different application patterns of downstream water level to water level and discharge of diversion tunnel.Tests show that higher downstream water level will affect water level of entrance and flow conditions of exit.Therefore,the average velocity and single wide power are lower.And the higher the water level,the greater the impact on diversion and closure is.
