摘要
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 multi stratum slope reinforced by anti slide pile,based on the principle of minimum potential energy,considering shear potential energy of sliding surface and interaction between anti slide pile and soil,three dimensional stability analysis method of anti slide pile reinforced multi stratum slope is proposed. This method and other methods are compared and validated,and analyzed the effect of anti slide pile parameters on slope stability. Results show that this method is feasible. When the anti slide pile is located in the middle part of the slope,the reinforcement effect is better and the stability is the best. When the distance between the anti slide pile is greater than 8m,the change of anti slide pile spacing has little effect on the safety factor of the slope.
