摘要: 根据白云鄂博矿边坡的实际情况,应用FLAC3D模拟分析了锚杆在不同锚固角和锚固长度时对边坡稳定性的影响,利用强度折减原理得出不同锚固状态下的边坡安全系数F,通过F与锚固角和锚杆长度之间的关系,得出该矿的最优锚固角变化规律以及锚杆长度对边坡稳定性的影响,为白云矿边坡锚固提供参考。

Abstract: According to the actual situation of Baiyun ore slope, the influence of the different anchoring angle and anchorage length of rock bolt on the ore slope stability is simulated by using the FLAC3D software.The safety coefficient F of slope under different anchoring conditions based on the theory of strengh reduction.In view of the relationship between the safety coefficient F and anchoring angle and anchorage length,the optimal anchoring angle change rule and the influence of the anchorage length on the ore slope stability are obtained.So,the research result in this paper can provide reference for the rock bolt installation of Baiyun ore.
Key words: Slope consolidate, FLAC3D, Anchor arrangement, Safety coefficient
