工程设计中常运用图解方法进行消力池水力计算。本文介绍的是河北农业大学水利系的图解方法。该法在图解图中有消力池深度图解、消力坎高度图解、综合消力池图解、消力池长度图解、收缩断面水深及其共轭水深图解,以及临界水深求解图。利用该法十分简便,其图解结果与(工作量很大的)计算结果相当一致,完全可以满足工程要求。现分别介绍如下: 1.利用该法求挖深式(降低护坦)消力池的池深S的求解图(如图解图的右半部所示)
Often used in engineering design Schematic diagram of the power pool hydraulic calculation. This article describes the graphic method of Hebei Agricultural University Department of Water Resources. The law in the diagram of the Schematic diagram of the depth of stilling pool, anti-ridge height diagram, the comprehensive diagram of the pool, the pool diagram of the length of the contraction, the depth of contraction and its conjugate water depth graphic, as well as the critical depth of water map. The method is very simple and its results are quite consistent with the computational results (great workload), which can fully meet the engineering requirements. Are introduced as follows: 1. The use of the law to dig deep type (reduce the tank protection tank) pool depth S solution map (as shown in the right half of the diagram)
