隧洞导流

不过水围堰隧洞导流方案洞径及围堰高度的多目标择优

Multi-objective optimal selection of cofferdam height and tunnel diameter under non-overtopped cofferdam condition

介绍了圆形隧洞导流时无压流的情况下水力计算底坡的快速判别方式。

The rapid discrimination method of the base slope in the hydraulic calculation on the free flow of river diversion circular section tunnel is introduced .

对明渠导流、隧洞导流、分期导流和施工度汛进行了详细论述；对施工导流方案的选择及施工度汛的主要经验进行了总结，可供水利工程技术人员参考。

This paper discusses in detail the river diversion through open channels or tunnels and in stages , and the flood prevention in construction period , and also summarizes some main experience on the selection of river diversion schemes and on the flood prevention in construction periods .

趋向较高水头截流，可减少导流隧洞或导流明渠工程量；

There is a trend of river closure with a higher water head in order to decrease the work amount of diversion tunnels or diversion channels ;
