基于频率统计法的短历时可能最大降水估算
Estimation of short-duration possible maximum precipitation based on frequency statistics method
摘要
Abstract
The Short-duration probable maximum precipitation(PMP)is the main basis for the design of drainage facilities in nuclear power plants.Based on the analysis of the rainstorm characteristics,weather causes and site data of a coastal nuclear power plant site,this paper used the Pearson-Ⅲ curve and moment method to calculate the numerical statistics of short-duration rainfall with different frequencies,and then calculated and analyzed the ratio of the design value of different durations of once-in-ten-thousands-year rainfall and the design value of 24-hour once-in-ten-thousands-year rainfall to obtain the possible maximum precipitation with different short durations.Finally,by comparing with the records of heavy rainstorms at home and abroad and the short-duration PMP results of other nuclear power plants,the calculation results were reasonable,which can provide reference for the analysis and calculation of short-duration PMP in other regions.关键词
