摘　　要：针对安太堡露天矿西北帮边坡远程监测区域,基于GIS空间分析模块,应用克里金插值法对边坡位移实测数据进行空间插值,对边坡位移影响因子进行栅格数据转化,统计分析各因子的敏感性.结果表明:边坡坡度、坡高对边坡位移的影响较大,随着坡度、高程的增大,边坡位移也会相应地增大;井工开采会导致坡体的变形,对边坡位移的发展起着重大的影响.分析结果与工程实际较为吻合,证实了该研究方法的科学性与合理性,能够用于指导边坡的防护与治理.According to the northwest remote monitoring area of Antaibao open-pit slope, Krige interpolation method is used to interpolate displacement monitoring data. Based on the spatial analysis module of GIS, contour data is transformed to grid data, and then statistical analysis of the sensitivity of different factors is done. The results show that slope and eleva- tion have a great influence on the displacement of the slope, with the increase of slope and el- evation, the displacement will increase correspondingly. Underground mining can aggravate the deformation of the slope, and the displacement of the slope is influenced greatly by un- derground mining. The results are identical with practical engineering. Thus, the results are proved to be scientific and reasonable, and it can provide guidance for the protection and con- trol of landslide.
