以保阜高速引线跨越唐河桥梁为例,来说明穿越江河桥梁进行防洪影响评价的计算内容和评价方法。本文首先进行防洪评价计算,然后进行水文分析、洪水分析、河势影响分析等工作,在此基础上做出防洪影响综合评价。经论证,桥梁的修建时河道防洪基本没有影响。最后对可能出现的问题提出了合理化建议。 Take Bao-Fu high-speed lead across the Tanghe bridge as an example to illustrate the calculation contents and evaluation methods of flood control impact assessment across the river and bridge. In this paper, first, flood control evaluation and calculation, and then hydrological analysis, flood analysis, river impact analysis, etc., on the basis of which to make a comprehensive evaluation of flood control impact. After verification, the river flood control basically did not affect the construction of the bridge. At last, some reasonable suggestions are put forward for possible problems.
