摘　　要：根据孝义港下游地区排涝区实际情况,对工程实施段排涝区设计排涝流量进行分析。分别采用径流系数法、降水扣损法两种方法对排涝流量进行计算,采用径流系数法计算结果较为可靠,即P=10%最大一日净雨量为122.8 mm,最大三日净雨量为202.7 mm。计算结果为工程设计和施工洪水确定提供参考。According to the actual situation of the drainage area in the lower reaches of Xiaoyi port,the design drainage flow of the drainage area in the implementation section of the project is analyzed.The two methods of“runoff coefficient method”and“precipitation deduction method”are respectively used to calculate the drainage flow.The calculation results of“runoff coefficient method”are more reliable,that is,P=10%,the maximum one-day net rainfall is 122.8mm,and the maximum three-day net rainfall is 202.7mm.According to the calculation results,it provides a reference for engineering design and construction flood determination.
