低洼道路排水能力快速核算模型构建与效果分析
Construction of rapid calculation model for drainage capacity of urban low-lying roads and its effect analysis
摘要
Abstract
With climate change driving more frequent and intense extreme rainfall events worldwide,flooding of low-lying urban roads has become an increasingly critical issue,severely impairing transportation efficiency,disrupting urban mobility,and threatening public safety.To overcome the limitations of existing methods,such as complex procedures,high data dependency,and slow response times,this study constructed a rapid calculation method for the drainage capacity of low-lying roads.The method screened core parameters,simplified the calculation model,and designed a standardized workflow,which significantly reduced the reliance on complex data and professional software and enabled rapid assessments for single or multiple road sections.The method was validated through modeling based on 51 rainfall scenarios and comparative verification with a mechanistic model.The results showed that the relative error in predicting the inundation area for typical roads was controlled within 50％,confirming the effectiveness and practicality of the proposed method.These findings provide efficient technical support for urban drainage and flood control planning,emergency decision-making,and system renovation,which is of great practical significance for enhancing urban resilience and safety prevention capabilities.关键词
