高桩码头结构中伸缩缝有关问题的探讨

Approach to Expansion Joint of Open Type Pier on Piles

高桩码头开伸缩缝的宽度及位置以往不为设计、施工部门所重视,致使天津港高桩码头伸缩缝位置构件破损严重。通过对天津港高桩码头伸缩缝工作状况的调查分析,提出了伸缩缝宽度的计算式,可供今后高桩码头伸缩缝改造及《港口工程技术规范》中有关伸缩缝条款的修改时参考。

Widths and positions of expansion joints of open type pier on piles are not taken seriously by the designing and conctruction departments,so that the elements with expansion joints in open type piers on pilts of Tianjin Port are badly damaged.From investigation and analysis of the working state of axpansion joints of open type piers on piles of Tianjin Port, the width formula is presented for reference in reconstruction due to expansion joints of open type piers on piles and in revision of the provisions in connection with expansion joints of Harbor Engineering Specifications.
