【摘要】为了验证抗滑桩的设计合理性及其在暴雨工况下的支挡效果，采用“K”法对桩身进行设计计算；应用有限元数值模拟方法，对设桩前后的滑坡稳定性进行二维有限元数值分析。数值建模过程中，岩土体和抗滑桩分别采用Mohr-Coulomb本构模型及弹性模型。通过对设桩前后滑体的位移及剪应力和桩身位移及弯矩的比较分析，得出研究结论：（1）在暴雨工况下，采用抗滑桩进行基岩滑坡治理是完全有效的；（2）运用抗滑桩“K”法进行抗滑桩设计计算是合理可行的；（3）在采取抗滑桩支护的基础上，结合使用其它支挡结构，如框架锚杆（锚索），滑坡的治理效果会更好。
Abstract：In order to prove the rationality of the anti-slide pile design as well as its retaining effect under the condition of rainstorm， the “K” method was taken into the design of anti-slide pile. And then the finite element numerical simulation method， through analyzing the stability of landslide that was treated by the anti-slide pile or not， was put into use in the case. In the process of numerical modeling， the rock and soil mass of slope was defined as the Mohr-Coulomb constitutive model while the anti-slide pile was supposed to be a elastic model.Comparing the displacement and shearing force of the slope in situation that was protected by the anti-slide pile with those without piles treated， then taking the displacement and bending moment that performed in the pile into account， some conclusions were carried out as follow：No.1.Under the condition of the heavy rain， the method of using the anti-slide pile was of great advantages in the landslide treatment；No.2.The K method for the design of anti-slide pile was scientific enough.No.3.Using other retaining structure such as Anchor Bar Frame Support Technology， the governance effect of landslide would be more excellent.
