摘要
本文介绍作者对我国水库设计洪水及标准进行研究所取得的主要成果,即:用皮尔逊Ⅲ型曲线求得的万年一遇洪水偏大,脱离我国实际;规范中人为硬性规定PMP必须大于万年一遇洪水不妥,反映到工程投资上,浪费太大;我国现在的设计洪水数据已经很大,今后不可能再大幅度地增大;以往我国水库垮坝的主要原因是设计洪水数据偏小,而不是设计洪水标准偏低。
he all-round comparison and intensive study of the current design flood and criteria for reservoirs in China suggest that the design flood once in 10000 years on Pearson Type Ⅲ Distribution Curve tends to be higher and deviates from the actuality in China. It is improper to artificially stipulate that PMF must be higher than once 1/10000 as it results in enormous extravagsnce of project investments. With great achievements in the respect of design floods in China, it will be impossible to expand such to a great extent in the future. In the built reservoirs, dam failures resulted mainly from lower design floods rather than inferior design criteria.
