根据调洪演算的结果,任庄水库按现有坝高和基本保持泄洪闸现有泄洪能力的情况下,在正常或非常运用情况下,任庄水库50年一遇设计洪水位为66.03 m,200年一遇校核洪水位为66.41 m,均高于水库现状允许最高静库水位,而且高于现状坝顶高程,因此防洪安全不能满足要求。文章就任庄水库除险加固工程拟采用4种除险加固方案进行比选,按泄洪闸建设规模、泄洪闸工程位置等方面比选,从中选出最优方案。
According to the result of flood regulation calculation, Renzhuang reservoir, under the existing dam height and basically maintaining the existing flood discharge capacity of flood gates, under normal or extraordinary operation conditions, the design flood level of Renzhuang Reservoir once in 50 years is 66.03 m, The once-in-200-year check flood level is 66.41 m, which is higher than the highest static water level permitted by the status quo of the reservoir and higher than the current elevation of the crest. Therefore, the flood control safety can not meet the requirements. Article Zhuang reservoir reinforcement and reinforcement project intends to use four kinds of reinforcement programs for comparison, according to the scale of construction of flood gates, flood gates and other aspects of the project comparison, choose the best solution.
