某港区雨水管道淹没出流计算方法探讨

A port of Rainwater Pipe Submerged Flow Calculation Method

依据水力学基本理论,介绍了雨水管道系统淹没出流状态下水位雍高值的计算公式,结合某港区雨水管道设计方案,提出在淹没出流状态下,应采取加大雨水管管径的措施,以达到减少水位雍高对雨水排放的不利影响[1]。

In accordance with the basic Hydraulic theories, this paper introduces a formula for calculat ing the rising water level of the rainwater piping system with submerged discharge.Combined with the piping de ？sign of some harbour district, It also proposes measures like enlarging the pipes should be taken in the circum ？stances of submerged discharge,In order to reduce the banked-up water level adverse effects on damage.
