摘要
构建了夫夷水新宁县城河段一二维耦合模型,开展了洪水风险分析计算,评估了洪水影响及洪灾可能造成的经济损失;考虑洪水影响社会指标和洪灾损失经济指标,提出了基于淹没人口风险期望和洪灾损失风险期望的新宁县城防洪标准优选方法,为城市防洪标准的选择提供参考。
This paper constructs a 1 D-2 D coupled model of Xinning reach of Fuyi River,analyzes and calculates the flood risk, assesses the impact and economic losses caused by floods, considers the social indicators of flood impact and the economic indicators of flood damage, and proposes the optimization method for flood control standards of Xinning County based on the expectations of population and loss risks, which provides a reference for selection of flood control standard.
