摘要:
边坡的稳定性问题关系到人们的生命安全,对其进行研究是非常有必要的。以白云鄂博铁矿的D区边坡稳定性分析为例,采用复合法进行研究,首先通过对其边坡进行现场节理的详细线测量绘制赤平投影图,来判断出可能发生破坏的位置;其次通过Sarma法进行平衡理论计算,稳定性系数结果为075;最后通过FLAC3D进行数值模拟计算,得出应力、应变云图,另对分析出可能破坏的两个位置进行剖面计算,计算后的稳定性系数结果分别为05、06。总之,边坡稳定性系数均小于1,可能发生失稳,需对其进行加固,保证矿山安全开采。
Abstract:
The stability of slope is related to people's life safety,it is very necessary to study this problem. Taking the stability analysis of D zone slope in Baiyun obo iron ore for example, the composite algorithm was adopted to carry out research. First of all, through the detailed onsite joint line measurment on the slope, a plane projection was drawn to determine the location where the damage may occur; Secondly through the Sarma method, the calculation accroding to the balance theory was conducted, and the stability coefficient of the calculation result was 075; Finally by FLAC3D numerical simulation, the stress and strain nephogram were obtained, and the profile calculation was performed on the other two positions of possible damage. The calculation results of stability coefficient were 05, 06 Anyhow, when the slope stability coefficient is less than 1, the instability may occur, and the mine need to consolidate it to guarantee the mine safety production.
