摘　　要：为了能在唐山港京唐港区典型的泥沙运动较活跃的细沙粉沙质海岸建设20万吨级深水航道,界定细沙粉沙质海岸的主要特征指标,系统研究细沙粉沙质海岸泥沙起动和输移规律。采用波浪潮流共同作用下细沙粉沙质海岸泥沙动床物理模型,模拟多年岸滩演变规律及其对航道骤淤的影响。利用波浪泥沙整体物理模型,模拟越浪携带泥沙和堤后二次波浪掀沙对内航道淤积的影响,合理确定第四港池防浪挡沙堤高程,并提出在复合沿岸输沙条件下的航道防淤减淤措施、挡沙堤布置原则以及适合于细沙粉沙质海岸的深水航道尺度确定方法。To build 200 000 ton deep-water channel on the typical sanay-suty coast m Jingtang District of Tangshan Port, in which sediment movement is active, the characteristics of sandy-silty coast of the sand-retaining breakwater is defined and the rules of the sediment＇s movement and transport are researched systematically. The wave-current interaction physical silty coast model with sediment transport and movable bed is used for studying the beach evolution of many years and its impact on the channel＇s sudden deposition. The overall wave-sediment physical model is used to simulate the impact of the overtopping wave carried sediment and the back-barrier secondary wave raised sediment on the internal channel sedimentation. Thebreakwater＇s height of the fourth harbor basin is determined reasonably. The channel＇s anti-silt measures, the breakwater layout principles and the deep channel scale＇s determining method for silty coast under complicated long shore sediment transport are presented.
