摘　　要：根据水力学理论,阐述了重力流雨水管道淹没出流的水力计算方法,并结合工程实例,介绍了低地坪高潮位地区雨水管道淹没出流的简化计算方法。提出低地坪高潮位地区的重力流雨水管道应优先采用小坡降、低流速、大管径系统,以尽可能降低水位壅高对管道的不利影响。Based on hydraulics,this paper demonstrated the submerged discharge calculation method for the gravity storm sewer,and introduced the simplified the submerged discharge calculation method for the gravity storm sewer in low terrace and high tide level area combination with the practical engineering projects.It was suggested that,in low terrace and high tide level area,the gravity storm sewer should employ flat slope,slow flow rate,and huge pipe diameter system preferentially,and the banked-up water level should be reduced as much as possible so as to alleviate the damage to pipes.
