泰州中干河闸站引排水对周山河通航的影响研究

以中干河闸站为例，采用平面二维水流数学模型的技术手段，对中干河闸站建成后引排水对周山河通航的影响进行系统研究。中干河闸站是泰州市城市水生态环境建设项目，位于中干河和周山河交叉处，闸站采用双向抽排型式。闸站引排水可能会对周干河通航产生影响，进而影响到闸站的运行。研究表明：泵站抽引排水对周山河的影响随着外河水位的降低而增大，当外河水位为3~5m，闸站引排水量为20～30m3/s时，对周山河航道基本无影响；当外河水位为1.5～2.0m，闸站引水量为30m3/s时，对周山河航道有一定的影响。

A Study of the Influence of the Zhonggan River Sluice Station on the Shipping in the Zhoushan River

This paper takes Zhonggan River sluice station for example, and utilizes the 2-D flow model to estimate the influence of drainaging and intaking water on the navigation. The station is one of the urban eco-environment construction projects of Taizhou City, situated on the intersection of Zhonggan River and Zhoushan River, which performs in a bi-directional mode including both drainage and diversion. The performance of the station has an impact on Zhoushan River’s navigation. The results show that, the effect of the pump station increases with the decrescence of outer water level. When the discharge equals to 20m3/s~30m3/s with a water level higher than 3m, the influence of sluice station is allowable to the correlative standard; when the water level of Zhoushan River is lower than 2m with a relatively large discharge, the influence will exceed the limits of criteria. The station’s performance should adjust with the outer water level.
