摘　　要：为研究强潮河口污水处理厂排江竖管的局部冲刷问题,采用物理模型试验的方法针对不利的洪水、潮流、河床高程等条件,对瑞安江南污水排放口竖管附近局部冲刷坑的冲刷深度、冲刷形态进行了冲刷试验研究。试验得出不利水文条件下的最低冲刷高程及冲刷坑大致形态,冲刷试验成果可作为竖管相关设计的依据。To study local scour of river discharge standpipes of a sewage treatment plant at strong tidal estuary,this paper used physical model tests for adverse conditions such as floods,tidal current and river bed elevation,and conducted experimental study on scouring depth and erosion form of local scour near Rui＇ an Jiangnan sewage outlet standpipe. The test got the lowest scour elevation and rough scour form under adverse hydrological conditions. The scouring test results can be used as the basis for related standpipe design,and can provide reference to similar projects of strong tidal estuary.
