Application of the Boundary Layer Theory to the Hydraulic Computation of Broad-crested Weir

边界层理论在宽顶堰流水力计算中的应用

Using boundary layer and critical depth of flow theories, the hydraulic calculations are carries out for streamlined broad-crested weir. The method open a new way in the calculation of the broad-crested weir.

采用边界层理论和临界水深理论，实现了流线形宽顶堰流的水力计算，此方法为宽顶堰流流量的计算开辟了一条新途径。

If a gate is to be installed on the crest, orifice flow can be trans-formed into broad-crested weir flow at any water heads, provided that the suggested limitations are taken into consideration in hydraulic design.

若堰顶设有闸门，如果在水力设计中考虑了上述极限控制条件，则在任意堰顶水头情况下，都可以完成从孔流到宽顶堰溢流的过渡。
