采用有限元法分析了抗滑桩加固后土坡的稳定性.土体被认为是理想弹塑性模型,服从Mohr-Coulomb屈服准则,加固土坡的排桩被简化成等效的板桩,当其达到极限容许弯矩时即认为达到弯断破坏,土坡安全系数的计算采用强度折减法.文中还讨论了抗滑桩类型、抗弯刚度、极限弯矩及排桩设置位置对加固土坡整体稳定性的影响. The finite element method is used to analyze the stability of soil slopes after the anti-slide piles are reinforced. The soil is considered to be an ideal elastoplastic model. According to the Mohr-Coulomb yield criterion, the piles reinforced on the soil slopes are simplified into equivalent piles. When it reaches the limit allowable bending moment, the bending damage is considered and the safety factor of soil slope is calculated by the method of strength reduction.The type of anti-slide pile, flexural rigidity, ultimate bending moment and the position of pile placement are also discussed. The overall stability of the impact.
