高桩码头新型分段缝结构研究

摘要

针对现有高桩码头分段缝结构的不足和工程需要，论文提出了主要由带U形槽的分段横梁和码头结构段端部纵梁组成的新型分段缝结构，并详细介绍了该结构的构造、特点和技术设计方法。结果表明，提出的新型分段缝结构不但满足相邻结构段的自由伸缩要求和不均匀沉降要求，而且可以有效控制相邻结构段之间的横向相对位移，具有受力明确、经济性好、设计施工方便等优点，值得推广应用。%Aiming at the shortcomings of the existing high⁃piled wharf joints structure and engineering need, new joints structure consisting of segmented beam with U⁃shaped slot and end girder were proposed in this paper. Characteristics and technology design method of the structure were introduced in details. Results show that the pro⁃posed new joints structure can not only satisfy the requirement of free expansion and uneven settlement between ad⁃jacent structures, but the transverse relative displacement between adjacent ones can also be controlled. It has sev⁃eral advantages of clear force, good economy, convenient design and construction and so on.
