基于全分布式洪涝模型的城市竖向规划研究OA

Taking the Shahe River basin in Guangzhou City as the research area,a fully distributed urban flood model was constructed based on Infoworks ICM.This study systematically analyses the causes of urban waterlogging and explores,from the perspective of urban vertical planning,how to effectively prevent and control flood disasters during the urban planning stage.Three collaborative optimisation schemes integrating"drainage network and vertical planning"were proposed,and their flood control effectiveness was analysed.The results indicate that the urban waterlogging cannot be fundamentally addressed solely by improving the drainage network alone;scientific and rational vertical planning is a key measure for waterlogging prevention and control.However,as local vertical adjustments may increase the overall risk to the regional drainage system,integrating flood prevention and control objectives into urban vertical planning is of great significance for mitigating flood disasters and enhancing urban resilience.
