摘要
双排抗滑桩在边坡支护中有着重要作用。针对某路堑复合岩层边坡设置双排抗滑桩,从边坡最大塑性变形、最大剪应力及安全系数出发,通过有限元软件,分析双排抗滑桩布设位置对边坡变形、受力的影响。结果表明:双排抗滑桩设置在边坡底部、中部和上部时,最大塑性变形和最大剪应力均发生在抗滑桩位置。双排抗滑桩布设在边坡下部位置时,对于最大塑性变形和最大剪应力,边坡稳定性均优于布设在边坡中、上部位。
Double-row anti-slide piles play a crucial role in supporting slopes.Focusing on the set-up of double-row anti-slide piles for a composite rock cutting slope,from the maximum plastic deformation,the maximum shear stress,and the safety factor of the slope,this paper used the finite element software to analyze the impact of the layout of double-row anti-slide piles on the slope deformation and stress.The results showed that when the double-row anti-slide piles were laid in the lower,middle,and upper parts of the slope,the maximum plastic deformation and maximum shear stress occurred at the location of the anti-slide piles.In terms of maximum plastic deformation and maximum shear stress,the slope stability when the double-row anti-slide piles were laid in the lower part of the slope was better than that in the middle and upper parts of the slope.
