基于模型及在线监测的校园海绵改造项目效果评估

Effect Assessment of Campus Sponge Construction Project Based on Model and Online Monitoring

海绵城市建设项目的效果评估是海绵城市建设的关键环节之一,关系到海绵城市试点建设的整体效果。以宁波某校园海绵改造项目为例,采用模型模拟方法评估海绵城市改造效果,结合在线监测数据验证模型参数,提高模拟结果的准确性。模拟与实际监测结果显示,通过低影响开发措施改造,该项目的年径流总量控制率、径流污染、径流峰值、内涝积水均得到有效控制,满足海绵城市设计目标。模型与在线监测联合法是评估海绵城市建设效果的有效手段和重要方式。

Effect assessment of sponge city project is one of key steps in the sponge city construction,which is related to the overall effect of pilot area. Taking a campus sponge construction project in Ningbo as an example,the assessment method based on model and combined with online monitoring data to improve the accuracy of simulation results is introduced. According to the results,the design objectives of sponge city,such as volume capture ratio of annual rainfall,runoff pollution,runoff peak,and waterlogging are effectively controlled by the low impact development( LID) measures. Thus the combined method of model and online monitoring is an effective and important way for sponge city construction assessment.
