摘要:
以常德市某院落为例，以问题为导向确定设计目标，在解析现状地形的基础上划分汇水分区，以源头分散为原则布设低影响开发(LID)设施并新增排水溢流设施。改造方案确定后以DigitalWater Simulation为模型构建工具，输入不同重现期的长、短历时降雨数据和全年降雨数据，构建海绵城市规划排水模型，对项目建设后的水文水质进行模拟评估。结果表明，该院落海绵化改造方案合理可行，典型年的降雨数据模拟结果显示，年径流总量控制率达到了86.3%，年SS总量去除率为48.5%，满足海绵城市建设目标要求。
Abstract:
A design goal of a courtyard sponge transformation scheme in Changde was decided by problem-oriented approaches. Catchments were divided based on the analysis of current terrain, and low impact development (LID) facilities were set up based on the principle of source dispersed control and addition of new drainage overflow facilities. After the scheme was determined, DigitalWater Simulation was used as a tool, and long and short duration rainfall data and annual rainfall data with different return periods were input to construct a sponge city planning drainage model. Hydrology and water quality were evaluated afterwards. The results showed that the sponge transformation scheme of the courtyard was reasonable and feasible. According to simulation results of rainfall data in a typical year, the volume capture ratio of annual rainfall achieved 86.3% and the removal efficiency of annual total SS was 48.5%, which met the requirement of sponge city construction goal.
