由于工程修建后必然对河道水位和流态产生影响,为评价拟建工程对河道行洪、通航等方面影响大小,优化工程结构设计,采用非正交曲线坐标下的平面二维水流数学模型,对船台滑道改造前后河段水流情况进行了数值模拟。计算结果表明,工程修建后对附近河段水位和流速影响均很小,不会对河道河势、通航、行洪等方面带来不利影响。
由于工程脩建後必然對河道水位和流態產生影響,為評價擬建工程對河道行洪、通航等方麵影響大小,優化工程結構設計,採用非正交麯線坐標下的平麵二維水流數學模型,對船檯滑道改造前後河段水流情況進行瞭數值模擬。計算結果錶明,工程脩建後對附近河段水位和流速影響均很小,不會對河道河勢、通航、行洪等方麵帶來不利影響。

In order to change the situation of limited production, Chongqing Dongfeng Shipbuilding Corporation plans to rebuild the existing berth and chute, which will influence the natural water level and flow patten near the project inevitably. For analyzing the influence of such project and optimizing the design of it, a 2-D non-orthogonal curvilinear coordinate flow mathematical model is used to simulate the stream conditions. The computational results show that there is no obvious influence to the water level and velocity after the rebuilding, and the project will not bring disadvantageous influence to the river regime, navigation and flood control.
