通启运河水利枢纽工程选址研究

Study on Site Selection of Tongqi Canal Hydro-junction Project

摘要:

对于城区内受限较多的河道，为改善水环境保障水安全，常采用泵闸合建的方式解决。水利枢纽的工程选址直接关乎其全生命周期的投入与效益。现以南通通启运河水利枢纽为例，基于满足自身功能性的要求，协调区域整体建设规划，结合二维水流数学模型验证流态及流速分布，具体研究工程选址，探求工程建设最优解。

Abstract:

In order to improve the water environment and guarantee the water security, the solution of pumping station and sluice co-construction is usually adopted for some urban rivers constrained a lot. The site selection of hydro-junction project is directly related to the investment and benefits of its whole life cycle. Taking Tongqi Canal Hydro-junction in Nantong as an example, based on the requirements to meet its own functions, the overall construction planning of the area is coordinated. Combined with the tow-dimensional flow mathematical model, the distribution of the flow state and velocity is validated, the engineering location is studied in detail and the optimal solution of engineering construction is explored.
