- 摘要:
- 为了提高雨季城市排水系统的弹性和韧性，削减合流制管网溢流和城市内涝，应用实时控制技术是一种智能化的解决方案。实时控制技术的有效实施对城市排水系统模型的运行时间和计算能力提出了要求。为了克服传统物理模型建模复杂、参数繁多、运行速度慢等问题，根据实际案例应用构建了一种基于马斯京根方法的概念模型，分析了其物理原理和参数特征，描述了概念化的具体过程。通过模型参数优化和整体可靠性分析证实了马斯京根模型对排水系统良好的模拟效果，并将其应用于控制策略优化。
- Abstract:
- To improve the flexibility and resilience of the urban drainage system in wet weather and reduce combined sewer overflow and urban flooding, the application of real time control (RTC) is an intelligent solution. The effective implementation of RTC technology puts forward requirements on the running time and computing power of the urban drainage system model. In order to overcome the problems of complex modeling, too many parameters, and slow running speed of traditional physical models, a conceptual model based on Muskingum method was built for an actual application,analyzing its physical principles and parameter characteristics and describing the conceptualization process. Through the optimization of model parameters and overall reliability analysis, the good simulation effect of the Muskingum model on urban drainage system was confirmed and it could be applied to control strategy optimization.
