摘　　要：阐述了某高陡边坡加固前后的稳定状态及预应力锚索加固方式,运用了极射赤平投影的理论分析法、FLAC3D有限差分数值分析法以及现场监测法等手段对高陡边坡稳定性进行了分析和评价,结果表明这三种方法能够有效分析高陡边坡的稳定性并相互印证,同时表明预应力锚索对高陡边坡竖直位移和水平位移等方面具有良好的加固和约束作用。The stable state of the high and steep slope before and after it is reinforced and the method of the reinforcement on the prestressed cable are expounded.The stability of high and steep slope is analyzed and evaluated by using the theory of stereographic projection,FLAC3D finite difference numerical analysis and field monitoring.The results shows that the three methods can effectively analyze the stability of high and steep slope and confirm each other.Meanwhile,it also shows that the prestressed cable has good reinforcement and restraint on high and steep slope of the vertical displacement and horizontal displacement etc.
