摘要
在广州港南沙港区一期工程建设过程中,常有外来取沙船只进入码头施工水域取沙作业,既干扰了现场的正常施工,又给码头安全带来了严重的隐患。用二维潮流泥沙数学模型模拟了南沙港区水域取沙船挖沙对南沙港区的水动力条件及泥沙运动的影响,分析其利弊,并对港区附近水域采沙规划提出合理性的建议。
During the construction of the Stage I Project of Nansha Harbor reach;non_native sand dredgers often enter the waters of construction area to carry out sand borrowing.This not only has disturbed the normal construction in the fiedl,but also brought about hidden danger to the safety of the ferry.A two_dimensional numerical model of flow and sediment is established to simulate the effects of sand borrowing in waters of Nansha Harbor reach on hydrodynamic conditions and sediment movement in Nansha Harbor reach and analize its advantages and disadvantages.Rational suggestions are put forward for sand borrowing in waters near the harbor reach.
