摘要
以宁波市甬江河段右岸拟扩建的宝达码头为例,通过数值模拟方法,分析研究了不同洪潮组合在不同边界条件下码头栈桥上下游水流的流态、壅水高度及河床冲淤强度。并通过对比码头栈桥扩建前后河段的水位、河势、栈桥区冲淤等变化,分析了宝达码头的扩建对甬江河段行洪的影响。
Taken Baoda Dock in Ningbo City, that is to enlarged, as a study case, the flow pattern, back-water height up-down- stream of the dock trestle and the intensity of desihing of the fiver bed under different boundary conditions are analyzed for the various combinations of flood and tide based on the numerical simulation. Furthermore, the impact from the enlargement of Baoda Dock on the flood discharge is analyzed through the comparisons made on the changes of the water level, river regime and desihing within the area of the trestle of the reach before and after the enlargement.
