Methods of urban flood control and drainage plan under the background of sponge city

随着我国城市建设的快速发展,城市水文环境受到了比较大的破坏,当遇到强降雨天气时会增加城市的洪涝灾害风险,城市防洪排涝工作难度也随之增加,而基于海绵城市背景下的城市防洪排涝规划可以显著提升城市雨洪的容纳能力和排泄能力。本文以扬州市城市规划为背景,对扬州市防洪排涝存在的安全隐患进行了分析,然后结合扬州市规划要求制定了相应的防洪和治涝措施,取得了良好的治理效果。

Urban hydrology environment is damaged greatly with rapid development of urban construction in China. Urban flood disaster risks can be increased in heavy rainfall weather. Urban flood control and drainage work becomes more and more difficult as a result. Urban flood control and drainage plan under the background of sponge city can improve urban rain flood containing capacity and discharge capacity significantly. In the paper, Yangzhou urban plan is adopted as the background for analyzing the safety hidden danger of flood control and drainage in Yangzhou.
