| 以前期数学模型研究为基础,在已有长江河口段模型中,对通州沙水道和白茆沙水道深水航道整治一期
工程可行性研究比选方案、推荐方案以及初步设计方案进行定、动床物理模型试验研究,从水动力变化、河床冲

| Experimental studies on 12. 5 m deep waterway regulation ofTongzhou shoal and Baimao shoal |

| Abstract: |
| On the basis of preliminary numerical simulation studies, movable and immovable bed experiments of the
Yangtze estuary have been taken as the alternative schemes, the recommended schemes and the preliminary design
schemes. Waterway regulation effects, beach protection and the influences of the regulation works upon river
regime, flood control, and ambient environment are analyzed and compared from aspects of hydrodynamic changes
and riverbed scour-and-fill process. The research results show that the requirements of 500 m ×12. 5 m deep
waterway can be met through a little dredging operation, and that the preliminary design schemes are relatively
reasonable. The related research achievements have been applied to the waterway regulation engineering design and
the decision-making of the waterway regulation. |
