摘要
横向排架作为高桩码头的主要受力单元是高桩码头结构设计的关键。通过建立全直桩桩基横向排架、叉桩桩基横向排架及扇形桩基横向排架三种有限元模型,分别计算其在特定水平荷载、竖向荷载作用下排架内力的分布情况。结果表明三种模型内力分布受水平荷载作用影响较大,受竖向荷载作用影响较小。在相同水平荷载作用下,全直桩桩基横向排架桩基轴向压力最小,叉桩桩基横向排架桩基及横梁弯矩最小。通过计算分析可知,合理的桩基布置型式的选择可以有效地协调桩基跟地基土承载能力的关系、协调桩基跟横梁内力的相互关系以及优化桩基自身的内力分布。
As the main force-bearing unit of high-piled wharf,transverse bent is the key to the structural design of high-piled wharf.By establishing three kinds of finite element models of transverse bent of full-straight pile foundation,transverse bent of forked pile foundation and transverse bent of fan-shaped pile foundation,the distribution of the internal force of the bent frame under the action of specific horizontal load and vertical load is calculated respectively.The results show that the internal force distribution of the three models is greatly affected by the horizontal load,and less affected by the vertical load.Under the same horizontal load,the axial pressure of the horizontal bent pile foundation of the full-straight pile foundation is the smallest,and the bending moment of the horizontal bent pile foundation and the beam of the fork pile foundation is the smallest.Through calculation and analysis,it can be seen that the selection of a reasonable pile foundation layout can effectively coordinate the relationship between the pile foundation and the bearing capacity of the foundation soil,coordinate the relationship between the pile foundation and the internal force of the beam,and optimize the internal force distribution of the pile foundation itself.
