不同作用力下高桩码头叉桩受力分析

高桩码头结构的复杂性、桩体与土相互作用的非线性以及外力的多样性,使得桩体受力相当复杂。文章探讨了桩土相互作用的数值模拟方法,采用ANSYS有限元软件,建立了高桩码头桩体与土相互作用的数值计算模型,并结合正交化试验,进行了不同荷载下码头结构受力的仿真计算,并通过数理统计分析,得到了叉桩桩顶受力随荷载改变的变化规律以及叉桩桩顶受力的极限情况,为分析高桩码头叉桩破损原因提供了参考依据。

Force analysis for inclined pile of high-piled wharfs under different forces

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.The numerical method in this paper was utilized to analyze the pile-soil interaction.With the help of a numerical computational model concerning the interaction force developed by the ANSYS FEM software and the orthogonalized method,the simulation analysis of the wharf structure under different loads was realized.Through the mathematical physics methods,the changing rules of load distribution on pile top under different loads and the limiting condition for the force of the inclined pile were obtained finally,providing reference for damage analysis of inclined pile.
