摘　　要：泥化夹层在城市建设、公路的边坡中分布广泛,为了研究抗滑桩对含多层泥化夹层边坡稳定性的影响,通过建立有限元三维数值模型,基于强度折减法研究了抗滑桩分布位置和间距对边坡稳定性的影响。结果表明:含多夹层的边坡破坏面呈折线形,抗滑桩能有效阻止边坡失稳;在L_(x)/L=0.375、桩间距为2倍桩径时,安全系数最大,支护效果最佳。In order to study the influence of anti-slip piles on the slope stability of multi-layer siltized intercalation,the influence of the distribution position and spacing of anti-slip piles on the stability of the slopes was studied based on the strength subtraction method by establishing a three-dimensional numerical model of finite element. The results show that the slope failure surface with multiple sandwiches is linear,and the anti-slip pile can effectively prevent the slope from being unstable. At L_(x)/L = 0. 375 and the pile spacing is twice the pile diameter,the safety factor is the greatest and the support effect is the best.
