| 摘 要： | 在岩堆体边坡地区建设高速公路、铁路和隧道,不仅仅在施工阶段要考虑边坡稳定性,而且在工程运营阶段也要考虑边坡的长期稳定性问题,因此对边坡的加固是非常必要的。本文主要对预应力锚索加固岩堆体边坡加固效果进行FLAC数值模拟,通过比较施加锚索前后边坡位移、潜在滑动面、锚索轴力、应力及安全系数变化来说明锚索加固的作用。

| Abstract: | The slope stability should be considered not only in the construction period but also in the operating period for highways,railways or tunnels in the slope area with the accumulation of rock mass,and the reinforcement for the rock slopes is necessary.The numerical simulation for the reinforcement effect with the prestressed cables is carried out by using the program FLAC.Through comparing the changes of the slope displacement,the potential sliding surfaces,cable axial forces,stresses and safety factors before and after the installation of the cables the reinforcement effect is illustrated. |
