| 摘 要： | 针对某铁多金属矿山开采边坡存在部分区域滑塌的基本现状，为及时分析边坡是否存在大规模形变灾害，使用三维激光扫描技术对该边坡进行形变监测研究。结果表明，三维激光扫描技术较好地弥补了传统单点监测模式的弊端，能够从不同时段DEM叠合图中判断形变的运动方向以及形变量大小，更好地预判形变运移方向以及演化规律；通过边坡形变监测对比，不同的DEM模型存在较明显的变化，共识别出5处微小形变区域，经过实地勘察后，与实地形变特征是吻合的，说明选择并使用该方法是合理的，能够识别出微小形变，可以在矿区其他边坡监测中推广使用。

| Abstract: | Aiming at the basic situation of partial regional landslide on the mining slope of an iron polymetallic mine，in order to analyze whether there is a large-scale deformation disaster on the slope in a timely manner，this paper uses 3D laser scanning technology to conduct deformation monitoring and research on the slope. The results show that the three-dimensional laser scanning technology makes up for the shortcomings of the traditional single-point monitoring mode，and can judge the movement direction and shape variable size of the deformation from the DEM superposition diagram in different time periods，and better predict the deformation movement direction and evolution law. Through the comparison of slope deformation monitoring，there are more obvious changes in different DEM models，a total of 5 small deformation areas are identified，after field investigation，it is consistent with the deformation characteristics of the field，indicating that the selection and use of this method is reasonable，can identify small deformation，can be promoted and used in other slope monitoring in the mining area. |
