南水北调中线工程交叉建筑物的综合防洪风险分析
Synthese Flood Risk Analysis of Crossing Structures along Middle Route of South to North Water Transfer Project
长距离引水工程沿途往往要跨越众多河系，极易受到洪水的冲击，这就需要对其综合防洪风险给出定量的评估。本文以可靠度理论为基础，根据渠道所经过的各条河流的水文、地质、地形、工程结构的随机特征，给出了引水工程交叉建筑物的综合防洪风险计算方法。并以南水北调中线工程河北省段为例，对该方法进行了应用。结果表明：集水面积较大河流上的交叉建筑物的综合防洪风险在1%以下，集水面积相对较小河流上的交叉建筑物的综合防洪风险也不高于2%，这说明南水北调中线工程河北省段是安全可靠的。
It is very often that long distance water transfer engineering was destroyed by flood due to too many rivers to cross. So synthese flood risk analysis is needed. According to stochastic characteristics of hydrology, geology, geograghy and structure, we present synthese flood risk assessment method of crossing structures along water transfering engineering based on realibility analysis theory. The method was applied in South to North Water Transfer Projcet Middle Route in Hebei province. Results show that the synthese flood risks of larger area valley are below 1% and that of smaller area valley are below 2%. So, from this point, Middle Route of South to North Water Transfer Projcet in Hebei province is safty.
