摘要
顺岸式港池是港口工程中常用的一种布置形式,港池的水流和泥沙淤积均具有其自身的特点,以往没有该类港池的泥沙淤积计算公式。本文利用二维数值水流槽试验研究顺岸式码头港池水流的特点,通过理论推导得出顺岸式码头港池的淤积公式。结合上海洋山港现场实测资料及泥沙水力特性的成果,利用该公式计算了洋山港区一、二期港池的淤积情况,计算结果与现场实测值吻合良好。表明本公式可在洋山深水港区使用,也可在其他类似港区的顺岸式码头港池中推广应用。
Parallel wharf basin is a common layout in harbour engineering, which current and sediment siltation is different from other basin layouts, and there is lack of the calculation formula for this kind of basin in the past. In this paper, the current characteristics of parallel wharf basin are studied by 2-D numerical tank, and the siltation formula of parallel basin is obtained by theory derivation. Combining with results of observed data and sediment hydraulic characteristics of Yangshan harbor in Shanghai, the siltation of phase-1 and phase-2 basin in Yangshan harbor is calculated by this formula, and the result is coincident to the observed data. it indicates that the formula can be applied in Yangshan harbor, and prompted application to other parallel wharf basins further.
