| 摘 要： | 为了查清南芬露天铁矿采场下盘334 m平台至370 m平台区域边坡浅层滑坡体发育情况，确定边坡潜在滑动面形态分布特征，采用地质雷达技术和数值分析方法，对334 m平台、346 m平台和370 m平台区域进行了现场探测和数值研究。依据地质雷达调查结果，分析出该区域存在1条连续的破碎带，并获得了相应滑坡体、破碎带和滑床的综合特征剖面图。数值计算结果表明:破碎带对该区域边坡稳定性影响作用强烈，导致边坡稳定性降低，同时破碎带构成了滑体的潜在滑移面。研究结果为南芬露天铁矿滑坡灾害的治理防治提供了重要的基础资料。

| Abstract: | In order to ascertain the development of slope shallow landslide from the footwall 334 m platform to 370 m platform in Nanfen open-pit iron mine and determine the speciation of potential slope sliding surface，the ground penetrating radar and the numerical methods are used to detect and analyze platforms of 334 m，346 m and 370 m.Ground penetration radar survey results show that there is a continuous broken belt in this region.The profile for landslide mass，broken zone and slide bed are achieved.Numerical simulation results indicate that broken belt has a strong influence on slope stability in the region and causes a decrease in slope stability.The potential landslide sliding surface is constituted by the crushed zone.The landslide ground penetrating radar detection results provides the basis reference data for prevention and control landslide disaster in Nanfen mine. |
