摘要:
目前,太湖区域常用的设计暴雨雨型是江苏省水文总站1984年刊布的《江苏省暴雨洪水图集》(以下简称“84图集”),该雨型已沿用30余年。由于气候变化,城镇化、工业化的快速发展,“84图集”雨型已经不能适应现阶段的设计需求。为摸索出一套适用于太湖区域的雨型分析方法,并和“84图集”雨型对比,根据江苏省水文局提供的位于太湖区域1956—1987年间的20场暴雨资料,采用概化的累计暴雨量百分数法分析该区域设计暴雨雨型。结果显示:概化方法得出的暴雨雨型形态与“84图集”雨型在雨峰位置上是基本一致的,由于不是只考虑极端情况,雨峰占比低于“84图集”,但概化雨型更能如实反映出实际暴雨的时程分布特征,且雨型形态更为合理。
Abstract:
At present, the commonly used design rainstorm pattern in Taihu Lake area is the "Atlas of Heavy Rain and Flood in Jiangsu Province"(hereinafter referred to as "Atlas 84")published by the Jiangsu Hydrological Station in 1984, which has been used for more than 30 years. Because of climate change, urbanization and industrialization, the rain pattern of the "Atlas 84" cannot adapt to the current design requirements. In order to find out a set of rainfall pattern analysis method suitable for the Tai Lake area and compare with "Atlas 84", the generalized accumulated rainstorm percentage method was used to analyze the design rainstorm pattern in this area based on 20 heavy rainfall events in the Tai Lake area from 1956 to 1987 provided by Jiangsu Hydrology and Water Resources Survey Bureau. The results showed that the rainstorm pattern obtained by generalizing method was basically consistent with the rain pattern of the "Atlas 84" in the rain peak position. Since extreme conditions were not only considered, the proportion of rain peaks was lower than that of the "Atlas 84", but the generalized rain pattern could more truthfully reflect temporal distribution characteristics of the actual rainstorm, and the rain pattern was more reasonable.
