通过实测水文泥沙资料、岸滩冲淤演变分析、泥沙计算、泥沙物理模型试验等手段对汕尾电厂煤港工程泥沙问题进行了研究。通过研究，了解了煤港工程海域──后江湾的水文泥沙基本特征、泥沙来源和泥沙运动规律，找出了煤港工程泥沙淤积成因，预报了煤港工程方案的泥沙淤积量，从泥沙淤积角度论证了煤港建设的可行性。 Through the measured hydrological and sediment data, the evolution of beach erosion and sedimentation analysis, sediment calculation, sediment physical model test and other means of Shanwei Power Plant Coal Harbor project sediment problems were studied. Through the research, we can understand the basic features of hydrological sediment, sediment source and sediment movement of the coal harbor project ─ ─ Houjiang Bay, find out the cause of sediment deposition in coal harbor project and predict the sediment of coal harbor project Siltation, from the perspective of sediment deposition demonstrated the feasibility of coal port construction.
