摘要
高桩码头结构的复杂性以及桩体与土相互作用的非线性,使得桩体受力相当复杂。文章分析了影响高桩码头叉桩受力的各种因素,通过建立ANSYS有限元模型计算各种工况下叉桩桩顶受力情况,得到了叉桩的破损机理,并结合各外力因素对叉桩不利受力进行敏感度分析,得到了叉桩受力的最不利工况组合和最敏感外力因素,对认识高桩码头叉桩破损的原因具有参考价值。
The complexity of high-piled wharf structure,the non-linearity of pile-soil interaction and the variety of external forces can lead to the rather complicated force distribution.Various factors influencing the inclined pile force of the high-piled wharf were analyzed in this paper.The ANSYS FEM Model was established to simulate the force of the inclined pile under various working conditions, and pile was concluded.Besides ,with the combination of the sensitivity analysis inclined pile, the worst force case and the most sensitive factor were obtained. for damage analysis of inclined pile. the damage mechanism of inclined of external force factors upon the Such results can provide reference
