南水北调中线一期工程王庆坨T型连接井交汇水力动态特性的数值研究

对带“品”字型导流均流墙的T型连接井交汇水流进行数值模拟计算，分析了连接井内的流态、流速分布等，结论证明，“品”字型导流均流墙能使来水在连接井内改变方向，从而均匀地进入下游三孔箱涵，圆弧设计对于水力流动影响较小，基本不增加水头损失。

Numerical study on hydrodynamic characteristic of confluence in Wangqingtuo T-junction Chamber of Phase I of Mid-Route of South-to-North Water Transfer Project

A numerical simulation is made on the confluence at the guide-walls in a triangle-layout in the junction chamber，and then the flow pattern，flow velocity，etc. in the chamber are analyzed. The conclusion shows that the guide-walls in a triangle-layout can make the inflowing water changing its direction in the chamber and thus evenly flow into the downstream tri-box culvert; for which the design of circular arc has less impact on the hydraulic flow with non-loss of the water head basically.
