摘　　要：在分析天津市区暴雨时空分布特征的基础上，建立了市区暴雨公式，推求了设计暴雨过程。结果表明：天津市实测最大点雨量主要集中在7月下旬～8月上旬这段时间，且不同时段实测最大点雨量在时间分布上比较集中。市区暴雨的强度较大，已达到大暴雨级别。市区设计暴雨过程的估算，可为相关部门的除涝规划提供依据。Based on the analysis on the spatial and temporal distribution features of rainstorm in the urban district of Tianjin, the rainstorm formula is established and then the design rainstorm process is derived, The result shows that the maximum measured point precipitations are concentrated in the period from the last ten-day of July to the first ten-day of August, and the maximum point precipitations measured in different periods of time are more concentrated for the temporal distribution, of which the intensity of the rainstorm is larger in the urban district and has already reached the level of heavy rainstorm. This estimation on the process of the design rainstorm in the urban district can provide a basis for making the water-logging control planning by the authorities concerned.
