摘要
基于物理模型试验,针对巴图凯水电站施工导流洞出口体型进行优化研究,通过多方案试验对比分析,最终提出的直坎+右侧贴角+右侧出口贴角+左侧直墙推荐方案,能够较好地解决下游河道冲刷及下游明渠水流流态问题,使下游河道冲刷深度和下游明渠水翅大幅减小,下游河道冲坑位置远离下游围堰和导流洞鼻坎末端.
Abstract
Based on the physical model test,the optimization of the outlet shape of the diversion tunnel for the construction of Batukai Hydropower Station is studied.Through the comparative analysis of multi-scheme tests,the recommended scheme of straight ridge+right angle+right outlet angle+left straight wall is finally proposed,which can better solve the problems of downstream river channel erosion and downstream open channel flow pattern,so that the downstream river channel erosion depth and downstream open channel water wing are greatly reduced,and the downstream river channel scour pit position is far away from the downstream cofferdam and the end of the diversion tunnel nose.
