摘要
为研究抗滑桩参数的变化对土质边坡的影响,采用数值模拟的方法对土质边坡在不同支护参数下的稳定性和变形进行了研究,研究结果表明,抗滑桩的设置位置应充分考虑土层的软弱面,边坡的稳定性随抗滑桩距坡脚位置的增大呈现出先增大后减小的变化,同时桩顶水平位移呈阶梯状增大变化;而桩间距过大或过小均不利于边坡的综合治理,且边坡稳定性对抗滑桩桩截面尺寸的变化敏感性较低.最终通过对各个工况的研究,得出了边坡的最佳参数方案,为土质边坡抗滑桩的设计工程应用提供参考.
In order to study the influence of the change of anti-slide pile parameters on soil slope,the stability and deformation of soil slope under different support parameters are studied by using numerical simulation method.The research shows that the soft surface of soil layer should be fully considered in the location of anti-slide piles.The stability of slope increases first and then decreases with the increase of the distance between anti-slide pile and slope toe,and the horizontal displacement of pile top increases in a stepped manner.However,too large and too small pile spacing is not conducive to the comprehensive treatment of the slope,and the slope stability is less sensitive to the change of the section size of the anti-slide pile.Finally,the best parameter scheme of the slope is obtained through the study of each working condition,providing the reference for the design and engineering application of anti-slide piles on soil slopes.
