| 摘 要： | 通过对唐山港京唐港区附近海岸演变进行调查和分析,结合唐山港京唐港区建港近二十年的现场观测资料,对港区附近的泥沙运动和港口航道泥沙淤积机理进行分析,对2003年10月强风暴潮期间,港口航道发生严重的泥沙骤於进行了研究,为解决港口航道特别是外航道的泥沙淤积问题,提出粉沙质海岸港区航道挡沙和固沙的工程措施,并通过物理模型对挡沙固沙措施的工程效果进行了模型试验。试验结果表明挡沙和固沙工程方案对航道泥沙减淤效果很明显,其中,挡沙方案目前已应用到唐山港京唐港区二期挡沙堤改造、三期挡沙堤的设计和建设工程中,已发挥其挡沙减淤的作用。

| Abstract: | The authors of the present paper describe the activities of investigation into the development of coast in the vicinity of Jingtang Harbor of Tanshan Port.The investigation data collected over a period of nearly 20 years by field observation have been used in the analysis of sediment movement in the sea area of the harbor and mechanism of siltation in the harbor and channel.A particular study has been conducted on the serious sudden siltation in the channel during the storm that occurred in October 2003.In order to solve the problem of siltation in the harbor and channel,especially in the outer channel,effective engineering measures for siltation abatement in port and channel built on silty sand beach have been proposed.These measures are proven effective by physical and digital model tests.They have been used in Phase 2 and Phase 3 breakwater works of Jingtang Harbor of Tangshan port. |
