Research of Horizontal Bearing Capacity of Single Pile Based on the Finite Element Strength Subtraction

为了研究单桩在水平承载力下的工作性能及极限承载能力,引入了有限元强度折减法来分析单桩的水平承载力.用MIDAS GTS有限元分析软件对单桩的水平承载力进行了数值分析和计算,通过实例确定水平承载桩的强度折减系数和极限承载能力,以验证强度折减法在桩基础中的应用及推广.

This paper looks into the working mechanism and ultimate bearing capacity of single pile under level bearing capacity,and analyzes the level bearing capacity of single pile by breaking and subtracting the strength of finite element. The level bearing capacity of single pile is obtained by the numerical simulation based on MIDAS GTS software. In the end,the coefficient of reducing strength and ultimate bearing capacity were achieved by an example,verifing the reliability of reducing strength method in the load calculation of pile.
