摘　　要：地面三维激光扫描技术可以高精度、高密度、高速度、非接触地测量滑坡表面三维空间坐标,从而得到滑坡模型地表的整体变形资料。文章结合滑坡模型试验,利用灰色模型GM(1,1)对模型中提取的两个监测点的三维坐标位移进行预测,经由实测值与预测值比较、误差检验、图形对比等得出结论:灰色模型可以应用于长期的滑坡控制点三维坐标位移预测中。3D laser scanning technology has been successfully applied in static surface measurement to get the overall landslide model surface deformation data. Combined with landslide modeling, the paper studied on the pre- diction of 3D displacement of two monitoring points by using the gray model GM（1, 1）. Trough the comparison between the measured and predicted values, the checking of errors and the contrast of graphic correlation, finally it was proved that the gray model could be used for long-term forecast of landslide 3D displacement.
