中文摘要：

地面三维激光扫描技术可以高精度、高密度、高速度地测量物体表面三维空间坐标，从而详细描述表面细部状况。它已经在静态形状测量中获得了成功的应用。目前，滑坡地表变形分析主要是采用GPS或全站仪测量的少量特征点来进行，缺乏整体变形资料。但滑坡变形体的诸多细节变化对正确的变形分析有着重要的作用，将该技术引入到滑坡变形监测与分析中，可充分利用滑坡体上的大量点自然地物作为监测点，来完整监测和分析其变形。作为一项新的研究内容，文章对此进行了相应的理论分析与实际测量，获得了初步满意的结果。

英文摘要：

3D laser scanning technology has been successfully applied to static surface measurement because it can measure 3D coordinate with high speed, high precision and high density to describe the surface detail. At present, the deformation analysis of the landslide surface is carried out mainly with some observed characteristic points by GPS or total station, but because of few data, this analysis is not complete. The detailed deformation of landslide has an important role for the correct deformation analysis. To introduce this technology to the landslide monitoring is significant for detailed deformation analysis, ira lot of natural rocks are used as monitoring points. In this paper, the theoretical analysis and the practical tests have been carried out; and the preliminary result has been obtained.
