集水槽的水力计算及最佳高宽比的进一步探讨

The discussion on the hydraulic account for catchment and optimal ratio between highness and width

根据集水槽内的水流特点,以横向入流的分析理论为基础,提出了计入水流沿程摩阻力影响求解槽首端水深的计算公式,通过与原型实测值比较,具有较高的精度。并通过优化方法给出了槽体横断面的最佳高宽比。

According to the motorial character of the flow in the catchment, basing on the analysis theory of transverse incoming flow, this paper poses the account formula of the water depth in slothead end with reckoning the flow friction during the whole course. From comparing the archetypal practical survey value, it proved that this has higher precision. And also from the optimized method, this paper shows the optimal ratio between highness and width of slot section.
