摘要

[目的]找出雨水管渠设计流量常用计算方法——面积叠加法和流量叠加法中存在的问题，对计算方法进行改进，使雨水设计流量计算结果更加合理。[方法]从下游管段暴雨强度的计算入手，对流量叠加法进行改进，同时提出基于穷举法的最大流量法。[结果]实例计算表明，除起始管段外，改进后的流量叠加法的各管段设计流量均小于面积叠加法，最大流量法各管段设计流量较面积叠加法平均增长7.0%，最大增长13.0%。[结论]运用最大流量法对雨水管渠进行设计，计算结果更合理，更安全，对缓解城市内涝具有重要意义。

Abstract

[Objective] To solve the issues in area superposition and flow superposition method in order to improve the discharge design in storm sewer.[Methods] Flow superposition method was modified by correcting the calculation method of storm intensity in downstream sewer. A maximum flow method based on exhaustion method was proposed.[Results] A case study indicated that the design discharge with improved flow superposition method was less than that of area superposition method

except for the initial sewer. The average design discharge based on maximum flow method was increased by 7.0%

and the maximum increase rate was 13.0%.[Conclusion] Maximum flow method is more reasonable and safer

and is of great importance for relieving urban flooding.
