水力模型用于排水系统的设计优化

在传统的城市排水管网设计和管理中，一般采用恒定流水力学理论计算管网的汇流过程，无法反映真实水流的突涨突落的非恒定流特点，因此在上海市虹南排水系统的规划设计中，应用城市排水系统水力模型模拟技术详细分析了雨水排水系统的水力学特征，诊断了管网瓶颈，优化了其管网布局、调度方式和工程方案，为提高虹南雨水排水系统的规划、设计、管理、运行技术水平发挥了重要作用。

Application of Hydraulic Model in Optimized Design of Drainage System

In traditional design and management of urban drainage network, the theory of the steady flow hydraulics is used to calculate the confluent process in drainage network, which can not reflect the unsteady flow characteristics of the real water flow. Therefore, the hydraulic model of urban drainage systems was used in the planning and design of the Shanghai Hongnan drainage system. By using the computer simulation technology, the hydraulic characteristics of the rainwater drainage system were analyzed, the drainage network bottlenecks were diagnosed, and the network layout, scheduling mode and project scheme were optimized. All these play an important role to improve the technical levels of planning, design, management and operation of the Hongnan drainage system.
