Numerical Simulation of Failure Model of Uplift Pile in Soil and Rock Foundation

中文摘要英文摘要

文中通过数值模拟方法,对土岩地基中抗拔桩的破坏模式及其影响因素进行分析.结果表明,在垂直静载和动态荷载两种情况下,抗拔桩的受力和变形情况存在显著差异.具体而言,垂直静载下,抗拔桩的轴力约为80 kN,弯矩约为20 kN·m,竖向位移约为2 mm,侧向位移约为1 mm;动态荷载作用下,抗拔桩受力和变形更加显著.这表明荷载大小、土体性质和桩身形状等因素对抗拔桩的破坏模式具有重要影响.

In this paper,the failure mode and influencing factors of uplift pile in soil and rock foundation are analyzed by numerical simula-tion.The results show that there are significant differences in the stress and deformation of pull-out piles under vertical static load and dynamic load.Specifically,under vertical static load,the axial force of the pull-out pile is about 80 kN,the bending moment is about 20 kN·m,the vertical displacement is about 2 mm and the la…查看全部>>
