| 摘 要： | 基于极限平衡法验算锚固边坡的安全系数,考虑了锚杆锚固角、锚杆长度、锚固位置、锚杆布设形式这些影响因素,利用GEO-SLOPE商业软件计算了边坡的安全系数,并得到了一些规律：①锚固边坡存在最优锚固角,不同长度锚杆的最优锚固角一致,大致在20°左右;②锚杆在坡面的位置对边坡安全系数也有很大影响,随着锚杆由坡顶向下移动过程中,安全系数呈现先增大后减小的趋势,在坡面中下部时的安全系数最大;③从锚杆的布设形式可以看出,中下部锚杆对边坡的安全系数影响最大。

| Abstract: | The safety coefficient of anchored slope was calculated based on the limit equilibrium method.This paper calculated the safety coefficient of anchored slope by GEO-SLOPE software,with the anchorage angle,anchor length,anchorage location and the anchor arrangement in consideration.The study results show that the optimal anchorage angle for anchored slope is roughly 20°;the safety coefficient increases at first and then decreases together with the anchor location from the top slope to the down slope,and the safety coefficient is the largest when the anchor is located on the lower part of the slope;the anchor located on the lower part effect the safety coefficient of anchored slope most greatly |
