针对天津南港工业区兴建及渤西油气处理厂迁建项目新建海底管道路由及登陆点选择的需要,利用数值模型对大区域(整个渤海)开展水动力数值模拟,进而推求小区域(渤海湾)的边界潮位,对小区域开展水动力数值模拟,同时引入泥沙输运模型,对渤海湾的泥沙运动进行数值模拟,最终获得子牙新河入海口区域行洪条件下泥沙的冲刷、淤积规律。分析得出:海底管道在子牙新河入海口区域登陆是可行性的,但其路由及登陆点应远离冲刷深度大于1 m的区域,基于此提出了两种推荐方案。
In view of the need of constructing new submarine pipelines and landing sites for the construction of Tianjin Nangang Industrial Zone and Boxi Oil and Gas Processing Plant, hydrodynamic numerical simulation of large area (Bohai Sea) is carried out by numerical model, and then the small area (Bohai Bay) , The hydrodynamic numerical simulation of small area was carried out. At the same time, the sediment transport model was introduced to simulate the sediment movement in the Bohai Bay. Finally, Sludge deposition law. The analysis shows that it is feasible for submarine pipelines to land in Ziya Xinhe estuary area. However, the routing and landing points should be far away from the area with erosion depth greater than 1 m. Based on this, two recommended schemes are proposed.
