- Abstract:
- 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.
