摘要
为实现滑坡体的整体位移监测,结合实际生产案例,采用三维激光扫描技术对滑坡体进行了数据采集和分析。结果表明,利用三维激光扫描技术可获取不同时期滑坡体的表面形态,生成数字高程模型(DEM),通过将这些DEM叠加分析,可以得到不同时期滑坡体的相对位移量和绝对位移量。由此可知,三维激光扫描技术可为滑坡体变形监测、灾害预报以及变形机理研究提供基础数据,具有较大的优势。
In order to achieve overall displacement monitoring of landslide body,combined with actual production cases,3D laser scanning technology was used to collect and analyze data on the landslide body.The results show that the surface morphology of landslide bodies in different periods can be obtained by 3D laser scanning technology,and digital elevation models(DEM) can be generated,and the relative displacement and absolute displacement of landslide bodies in different periods can be obtained by superimposing these DEM.It can be seen that 3D laser scanning technology can provide basic data for landslide body deformation monitoring,disaster prediction and deformation mechanism research,which has great advantages.
