| 摘 要： | 从能量损失的途径出发，把挑流能量损失过程分成4个阶段，并引入流速修正系数，修正无能量损失情况下求出的流速，从而得到入水前的水流流速。在得到冲坑内的能量损失后，由单位体积消能率来推算水体体积。再用几何方法求得水体最大冲刷深度，从而得到冲坑深度。

| Abstract: | Four stages are divided for the process of ski-jump energy loss. Correction coefficient of flow is introduced for modifying flow under the condition of no energy loss, so that flow speed before entering water can be obtained. After obtaining energy loss inside the scour hole, volume of water bodies can be calculated from unit volume energy dissipation rate. Afterward, geometrical method is adopted to derive the maximum scouring depth, and then the depth of scour hole. |
