摘　　要：唐山港京唐港区20万t级进港航道是在我国粉沙质海岸上建成的最大规模的人工航道。针对本港区20万t级进港航道前期研究、设计和建设实施中遇到的主要技术问题,如航道选线、主尺度设计、防沙堤口门布置、航道口门段的泥沙骤淤和横流等,进行深入细致的分析研究并提出解决方案。本工程的成功建设对在泥沙运动机理较为复杂的粉沙质海岸上建设高等级航道具有一定的借鉴意义。Jingtang Harbor 200 000 DWT approach channel of Tangshan Port is the biggest large-scale man made channel which is constructed on silty coast in China, intensive analysis and research are carried out, which focus on main technical problems occurred in the early-stage study, design and construction of 200 000 DWT approach channel such as line selection, main dimension design, layout of sediment trapping breakwater entrance, sudden sedimentation and cross current at channel entrance etc.. In addition, the related solution is put forward. The above success will provide references for high-grade channel constructed on the silty coast with complex sediment movement.
