在喷射超临界水流条件下,作用在泄水底孔下游端棱锥形消力墩上的力主要取决于水的流速、消力墩高度等因素。本试验是在喷射超临界水流条件下进行的。模型的比尺为1∶50,模型中的五个泄水底孔的下游端均布置了棱锥形消力墩,其宽度为150毫米,高为80毫米。试验分两种形式进行,即消力墩的布置位置和其底部面积是相同的,但其
Under the condition of jetting supercritical water flow, the force acting on the pyramid-shaped end of the pyramid at the downstream of the discharge hole mainly depends on the flow velocity of the water and the height of the piers. This test is carried out under the condition of jetting supercritical water. The scale of the model is 1:50, and the pyramid-shaped dissipative piers are arranged at the downstream ends of the five drainage holes in the model with a width of 150 mm and a height of 80 mm. The test is carried out in two forms, namely, the location of the piers is the same as that of the bottom of the piers. However,
