摘　　要：城市暴雨强度公式是城市雨水排放系统的设计依据,其准确性直接关系到城市排水系统的安全性。首先从不同选样方法、不同理论频率分布等方面,确立了上海市短历时暴雨强度公式的基本编制方法。然后在此基础上研究了上海市降雨资料在时间和空间上的变化对暴雨强度公式的影响,提出了具有典型性、代表性的上海市短历时暴雨强度推荐公式。The urban stormwater intensity formula is the important basis for urban rainwater drainage system design, so the accuracy of the formula poses a great impact on the safety of urban drainage system. Through deducing stormwater intensity formula under different sampling methods, theoretical frequency distributions and so on, the compilation method of Shanghai short-duration stormwater intensity formula was identified. On this basis, the effect of time and spatial variations of Shanghai rainfall data on the stormwater intensity formula was studied. Then, the recommended, typical and representative Shanghai short-duration stormwater intensity formula was presented.
