Tangshan Port Jingtang Port Area 18#-19# berths are the deep-water sheet-pile wharfs which firstly adopt the technology of separated relief diaphragm retaining wall structures. They are also an important part of deep-water sheet-pile wharf structure innovation research. Through analyzing and researching the berths' systematic prototype testing results that are done in the stage of wharf apron space dredging and after one year operation, the structure internal force and deformation detail of front sheet-pile wall are further obtained and grasped. The test results show that the structure internal force and deformation of the wharf front wall are smaller at initial operating stage. The space of wharf structure design may be further optimized subject to the internal force and deformation after wharf structure keeps stable condition.%唐山港京唐港区18#-19#泊位是我国首个采用分离卸荷式地下连续墙结构建设的深水板桩码头,是深水板桩码头结构创新相关研究的重要组成部分.通过分析研究该泊位在码头前沿疏浚期间和投入运营1 a后所进行的系统性原型测试成果,进一步了解和掌握码头前板桩墙的结构内力和变形情况.测试结果显示,在运营初期码头前墙的内力和变形均较小,进一步优化码头结构设计的空间取决于码头结构稳定后的内力与变形.
