Embodiment Construction

[0033] A statistical method for urban design rainstorm patterns, based on not less than 30 years of rainstorm records, comprising the following steps: 1) Determination of the field rain process, according to the annual record data, the step length of 5-minute precipitation for urban design rainstorm patterns The corresponding selection of the process is the annual maximum rainstorm sample for each specified duration of the rainstorm formula; 2) The rainfall process collection, according to the rainfall date and duration process of the annual maximum rainstorm sample for each specified duration, adopts the whole period step length A 5-minute rainfall process sample, or a rainfall process with a 5-minute sliding whole-point step using the integrated sample, can obtain a total of 288 rainfall data for the maximum rainfall day of the year; 3) Rain type statistics, for the above obtained 288 rainfall data, with 12 standard time periods as the specified duration, and the 12 standard ...

Abstract

The invention discloses a city design rainstorm pattern statistic method. Based on rainstorm record materials of more than 30 years, the method comprises the following steps of:1) determining rainfallprocesses; 2) acquiring the rainfall processes; 3) carrying out statistic on rainfall patterns; and 4) determining rain peaks, and correspondingly substituting rainfall values solved by a city rainstorm intensity formula into allocation proportions of design rainstorm patterns, respectively, so as to obtain a city design rainstorm time-history rainfall distribution, namely, a design rainfall pattern. According to the method, design rainstorm patterns according to objective realities of districts are established according to practical conditions of the districts, and a method for carrying outstatistic on rainfall patterns and simplifying samples is provided.

Description

technical field [0001] The invention relates to the technical field of rainstorm statistics and analysis, in particular to a statistical method for rainstorm patterns in urban design. Background technique [0002] The design rainstorm pattern, that is, the time course distribution of rainfall, refers to the change process of rainfall over time within the design rainfall duration period, which reflects the process of rainfall occurrence, development, and extinction. Due to the influence of many factors, the shape of different rainfall processes They are all different; the purpose of designing rainstorm pattern analysis is to discuss the time distribution relationship of total rainstorm rainfall, and its purpose is to design a rainfall distribution relationship that can represent the rainfall distribution characteristics of the region and can form the designed flood peak discharge, which is better representative The designed rainstorm pattern should be able to reflect and summ...
