摘要
针对层状岩体边坡的稳定性,充分考虑层状岩体边坡的地质情况,通过数值建模,建立了边坡长短锚杆复合支护的优化方案,锚杆相间布置,长度分别为6 m,2 m,倾角为20,°通过计算,边坡加固后处于稳定状态.计算结果与工程实际表明:长短锚杆复合支护的数值模拟技术对工程有一定的指导作用.
For the stable character of layer rock slope,the geological situation of layer rock slope is analyzed,through numerical calculation model,the optimal scheme of long-short compound bolt reinforcement is set up,and with the length of six meters and two meters separately and inclination angle of 20 degree,the reinforced slope is stable.The numerical calculation and engineering results show the long-short bolt reinforcement is useful to slope engineering.
