| 摘 要： | 分析了锁坝下游的冲刷机理，认为锁坝下游的冲刷主要是由涡漩水流造成的，并从涡漩环量在冲刷前后相等的概念出发，导出了锁坝下游冲刷深度的计算公式，并利用水槽试验资料对公式的系数进行了率定和检验，获得了较好的结果。

| Abstract: | The mechanism of the erosion downstream of the closure dikes is analyzed. It is concluded that the erosion is caused by vortex flow. Based on the concept of conservation of vortex circulation after erosion and prior to erosion, the formula for calculating the scouring depth is deduced. The validity of the formula is verified by flume experiment data. |
