高桩码头分缝处工后缝宽有限元分析

Finite element analysis of post-construction aperture in high-piled wharf joints

针对高桩码头伸缩缝处的挤压破损问题,结合实际工程中高桩码头设计方案,运用有限元方法,对码头面板在分缝处发生挤压接触、临界接触和没有接触3种状态进行研究,从理论上分析不同工后缝宽对码头面板内力的影响规律,并提出确定一个合理工后缝宽的新思路,为码头分段设计和施工条件控制提供了依据。

The squeezing damage in expansion joints of high-piled wharf is the general weakness in actual projects,which has a serious impact on the normal use of wharf.To solve this problem,combining the practical engineering design of the high-piled wharf,using the finite element method,we study the aperture comprehensively of three states,i.e.,extrusion contact,critical contact and no contact of the wharf panel,analyze the variation of internal forces of wharf panel with different post-construction apertures theoretically,and propose a new idea on determination of a reasonable post-construction aperture,which provides the basis for the design of wharf segments and construction control.
