摘　　要：针对现有海绵城市系统设施设计方法单一、集水排水性能评价方法缺失的问题,依托上海市虹口区市政道路配套大修工程项目,基于BIM技术平台,设计优化了海绵城市系统设施三维模型,构建了三维族库;运用编程语言对BIM平台进行二次开发,对建立的改良道路三维模型进行降雨模拟,评估改良道路设施的集水排水能力;并提出了基于BIM平台开发的海绵城市应急调控系统,对上海虹口区城市易涝程度进行了模拟评价。研究表明:BIM平台可通过三维族库指导海绵城市系统设施的标准化建设;二次开发的BIM平台可对海绵城市系统设施的排水能力进行可视化模拟呈现,并统计分析排水效果;基于BIM技术的应急调控系统可评估城市易涝风险,系统解决海绵城市雨洪控制、内涝风险等问题,实现海绵城市绿色高效管理。The existing sponge city system has the problems including single facility design method and lack of evaluation method of water collection and drainage performance.Based on a municipal road overhaul project in Shanghai Hongkou District,a three-dimensional model of sponge city system facilities was designed and optimized,and a three-dimensional library was constructed through BIM technology platform.The BIM platform was secondary developed by using programming language,and rainfall simulation was carried out by the established three-dimensional model to evaluate the water collecting and drainage capacity of the improved road facilities.An emergency control system of sponge city was proposed based on BIM platform,and waterlogging degree of Hongkou District in Shanghai was simulated and evaluated.The BIM platform could guide the standardized construction of sponge city system facilities through the three-dimensional library.The secondary developed BIM platform could visualize and simulate the drainage capacity of the sponge city system facilities,and statistically analyze the drainage performance.The emergency control system based on BIM technology could assess the risk of waterlogging in cities,systematically solve the problems of flood control and waterlogging risk in sponge cities,and realize green and efficient management of sponge cities.
