摘要
杭州湾为著名强潮海湾和粉沙淤泥质海岸,开敞式栈桥码头应合理布置,以保证码头前沿良好的水流泥沙条件和营运条件。本文针对规划杭州湾北岸某开敞式长栈桥码头布置,采用二维潮流泥沙数学模型,计算分析不同布置方式、轴线走向和引桥数量条件下各规划码头及已建码头前水流泥沙条件,并对码头平面布置进行优化,成果可供类似工程参考。
Hangzhou Bay is well known as a coast with strong tide and mealy sand silty base.To build a long open trestle berth there requires reasonable layout in order to guarantee good conditions of current,sediment and operation along the berth face.Based on the layout plan of one long open trestle berth along north shore of Hangzhou Bay,two-dimensional mathematic model of tide and sediment is used to calculate and analyze the conditions of current and sediment along the planned berths and the existing berths in the case of different layouts,directions of axis and the number of bridge approaches.In addition,the analysis results apply to the optimization of plane layout of the above berths,which will serve as a reference for similar projects.
