| 摘 要： | WES型复合堰是由WES堰的堰顶增加一平段衍变而成。通过改变堰顶厚度以及上游堰高形成一系列不同体型的WES型复合堰,由过堰水流流态和流量系数的变化规律,探讨了将WES型复合堰划分为WES型复合实用堰与WES型复合宽顶堰,及将WES型复合实用堰划分为高堰与低堰的划分标准,并在高、低堰的划分标准中考虑了堰顶厚度的影响。此外,按堰型分类给出了设计水位下流量系数的拟合公式,为进一步研究奠定了基础。

| Abstract: | WES (Waterway Experiment Station) compound weir is evolved from WES weir by adding a flat segment on the crest. Different WES compound weirs are formed by changing the crest thickness and the upstream weir height. In the present research,it is classified into WES compound practical weir and WES compound broad-crested weir according to the change of flow regime and flow oefficient. The standard to classify the WES weir into high weir and low weir in consideration of the crest thickness is also discussed. In addition,the fitting formulas of discharge coefficient under design water level are given for the above weir types. This research lays a foundation for further researches. |
