叉桩和平联撑在高桩码头中抵抗水平力作用分析

摘要

当高桩码头承受较大水平力荷载作用时,码头因位移大而存在安全隐患.为此,研究叉桩和平联撑在高桩码头中抵抗水平力作用大小.运用易工水运工程结构CAD集成软件建立高桩排架空间结构模型,计算分析叉桩排架结构在水平力作用下,码头横梁、桩基的内力和位移大小随叉桩的斜度和转角改变的规律,同时对比叉桩和平联撑在高桩码头中抵抗水平力大小.结果表明:叉桩排架结构抵抗水平力产生的位移作用远大于设置平联撑的排架结构.%The high-piled wharf faces potential safety hazard due to large displacement while subjected to large horizontal force.So,this paper carries out the research on the magnitude of resistance to horizontal force of batter-piles and horizontal braces in high-piled wharf.The influence of the inclination and rotation angle of the batter-piles on the internal force and displacement of the fascia beams and piles is discussed in this paper,basing on the high-pile bent frame structure model established by CAD integrated software for transport engineering structures. Meanwhile,the comparison about magnitude of resistance to horizontal force between batter-piles and horizontal braces is conducted.The result shows that the effect of reducing the displacement of the bent structure with batter-piles is much better than the structure with horizontal braces while subjected to horizontal force.
