采用有限元软件ANSYS,应用强度折减法原理,对不同倾角微型桩加固边坡进行数值分析,计算了天然边坡稳定系数以及竖直、倾斜微型桩加固边坡后的稳定系数,进而对采用倾斜微型桩加固边坡的稳定性进行评价。计算结果表明,天然边坡的稳定系数为1.04,而竖直桩加固边坡的稳定系数为1.17,采用倾斜角度不同的微型桩加固边坡后的边坡稳定系数与竖直桩相比,都有不同程度的提高,当微型桩倾斜角度从10°增加到60°时,边坡的稳定系数从1.22增加到1.65,边坡稳定性有明显提高,达到了边坡加固的效果。
The finite element analysis software ANSYS is used to analyze the slope stability of micro-piles with different inclination angle by using the principle of strength reduction method. The stability coefficient of natural slope and the stability coefficient of vertical and inclined miniature piles reinforced slope are calculated, The stability of micro pile reinforced slope is evaluated. The calculation results show that the stability coefficient of natural slope is 1.04, while the stability coefficient of vertical slope is 1.17. Compared with vertical pile, the stability coefficient of slopes after using micro-piles with different inclination angles are The slope stability factor increased from 1.22 to 1.65 and the stability of the slope improved obviously and the slope reinforcement effect was achieved.
