| 摘 要： | 大型地下水电站设计中常将施工导流洞与水电站尾水系统相结合,以减少工程量,加快施工进度,节约工程投资.如果能够利用导流洞减小调压室断面积,无疑具有重大的实用价值.通过数值仿真计算深入分析了水电站利用施工导流洞减小尾水调压室断面积的可行性,提出了在施工导流洞中增加挡流板来改善导流洞水流流态的工程措施.研究表明:利用施工导流洞至少可以减小调压室直径10%以上.该技术可推广应用于我国某些大型地下式水电站的建设中.

| Abstract: | Large underground hydropower stations always combine the diversion tunnel and tailrace system to reduce construction quantity,speed up construction schedule and save project cost when designing.It's certainly of significance if using the diversion tunnel to reduce the surge chamber's cross-section area.The feasibility of using the diversion tunnel to reduce the tailrace surge chamber's cross-section area is analyzed;and the engineering measures of mounting a baffle is put forward to improve the diversion tunnel's flow regime.The result shows that it can reduce water surge chamber diameter by 10% or more by using the diversion tunnel.The technology can be popularized to some large-scale underground hydropower stations. |
