为了分析抗滑桩加固边坡的稳定性,基于最小势能原理,考虑桩土之间的相互作用和滑面储存的剪切势能,提出了抗滑桩加固多地层边坡的三维稳定性分析方法。将该方法与其他方法进行对比验证,并分析了抗滑桩相关参数对边坡稳定性的影响。结果表明:该方法是合理可行的;当抗滑桩位于边坡中部时,对边坡的稳定性更好;当抗滑桩的桩间距大于8 m时,抗滑桩间距的变化对边坡安全系数的影响较小。
In order to analyze the stability of anti-slide piles strengthened slope, based on the principle of minimum potential energy, considering the interaction between pile and soil and the shear potential of sliding surface, a three-dimensional stability analysis method . The method is compared with other methods to verify and analyze the influence of anti-slide pile parameters on slope stability. The results show that this method is reasonable and feasible. When the anti-slide pile is located in the middle part of the slope, the stability of the slope is better. When the spacing of the anti-slide pile is more than 8 m, The effect of safety factor is small.
