摘　　要：因河道排涝系统与管道排水系统均单独设计,两个系统采用的选样方法、设计暴雨历时及边界条件不同,造成排水与排涝标准的不衔接。对厦门市长系列雨量资料进行统计分析,采用年多个样法与年最大值法得出短历时不同选样方法重现期的对应关系。在此基础上,统计雨强较小、降雨历时较长、总降雨量较大的次雨量绘制频率曲线,即考虑河道高水位对管道排水的破坏率的影响下,分析管道排水与河道排涝重现期的对应及衔接关系,作为河道排涝设计标准的依据。结果表明,考虑河道与管道规划施工的衔接,当管道的设计标准为1、2、3、5年时对应的河道设计标准分别为5、10、15、20年。The river drainage system and the pipe drainage system are designed respectively, with different sampling methods, design storm duration and boundary conditions, which leads to the divergence between the drainage and criterion of water log control. Annual multisampling method and annual maximum value method are used to determine the corresponding relationship between the return periods of different sampling methods by statistical analysis of the long series of rainfall data of Xiamen city. And then the frequency curve is derived through statistical analysis of individual rainfall, which has lower intensity, longer rainfall duration and larger precipitation. That is, considering the influence of river flood water level on the destruction rate of pipe drainage, the corresponding return period relationship between pipe drainage and river water log control is analyzed, which is used to be the basis of the river criterion of water log control. The results show that when considering the connection of planning and construction of river and pipeline, if the design criteria of pipeline is la. 2a. 3a and 5a. the cnrresnnnding design criteria of river channel is 5a. 10a, 15a. 20a.
