首先分析了龙滩水库的防洪效果,然后综合考虑各方面因素制定了防洪效果最优的大藤峡水库防洪调度方式,并通过调洪演算分析了大藤峡水利枢纽15亿m3防洪库容所能达到的最大防洪能力.结果表明,大藤峡15亿m3防洪库容基本可以满足“将梧州100年一遇洪水削减为50年一遇,兼顾削减梧州其他类型100年一遇以上洪水”的核心防洪目标,同时对于桂平、平南和藤县县城的防洪作用可以做到将30～50年一遇洪水基本削减到30年一遇,大部分削减到20年一遇以下.
Firstly, the flood control effect of Longtan reservoir is analyzed, and then the flood control dispatching mode of Dato-Gouxia Reservoir which has the best flood control effect is worked out by comprehensive consideration of various factors. The flood control capacity of 15MWm of Dato-Tang Gorge Reservoir can be reached through the flood regulation calculation The results show that the 1.5 billion m3 flood control capacity of the Big Teng Gorge basically meets the core flood control objectives of “reducing floods once in a decade in Wuzhou to once in 50 years and reducing floods of more than 100 years in other types of Wuzhou” At the same time, the flood control effect of Guiping, Pingnan and Tengxian counties can basically reduce floods once in 30-50 years to 30-year floods and most of them to less than 20 years.
