摘要
在现场踏勘和钻孔资料分析的基础上,选择了多条有代表性的详细线,在金堆城露天矿边坡开展了节理裂隙调查与分析工作。利用玫瑰花图和施密特投影等密度图,重点分析了各详细线和各帮边坡的节理裂隙产状分布规律;结合边坡产状、岩体摩擦角及各详细线处的地质情况,对边坡松动岩体潜在的破坏模式进行了研究,并给出了支护建议。研究为岩体质量分级和凹陷露天矿边坡形状优化提供了重要的参考依据。
Based on the field reconnaissance and borehole data, some representative detailed linears were chosen and the investigation work of engineering geological condition was carried out. By using the rose diagram and the schmidt projection isodense diagram, the distribution rules of the joint fissure of all detailed linear and working slope were analyzed emphatically. Combining with the occurrence of the slope, friction angle of rock mass and the geological condition of detailed linear, the potential failure modes of slope were studied and some supporting measures were advised. The study can be regarded as the references for rock mass quality classification and the open - pit slope shape optimization.
