[Abstract]:In Zhuhai, from 1984 to 2015, the design rainstorm level of two standard contiguous levels of drainage and drainage was calculated by using the combination of three periods of heavy rain, namely, 1 h-1 / 1 / 12 / 1 / 1 / 12 / h) of three combined rainstorms in Zhuhai for the purpose of calculating the design rainstorm level of the two levels of contiguous design of drainage and waterlogging. The Archimedes extreme Copula and Kendall distribution function are used to construct the joint probability distribution model of different duration rainstorm combinations. This paper analyzes the encounter probability, "or" recurrence period "and" secondary recurrence period "of each diachronic rainstorm combination, and calculates the design rainstorm value of each combination by the method of maximum possible probability. The results show that the cumulative frequency corresponding to the secondary recurrence period represents more accurately the risk rate of different duration rainstorm combinations under specific design frequencies. The design values of the second recurrence period, which were calculated to be 2 years, 3 years, 5 years, 10 years, 20 years, 50 years and 100 years, respectively, were between the design values of "or" recurrence period and "recurrence period". The relative error of the design value of the combination reckoning is 3.1 / 7.1h / s / 12h). The relative error of the design value of the combined calculation is 3.39.3U / R / L / 1h-R24h). The relative error of the design value of the combination is 3.9 / 12.0 / r / h, and the relative error of the design value of the combined calculation is 3.9 / 12.0 / h / h, and the relative error of the design value of the combined calculation is 3.39.3h-R24h. The design of different duration rainstorm combinations calculated in the secondary recurrence period provides the optimal selection standard and design reference for the risk management and pipe and canal size of waterlogging engineering.
