三维激光扫描技术及其在岩土工程中的应用

地面三维激光扫描技术是一项较新的数据收集与分析技术，它可以快速扫描目标，获得高密度，高精度的目标空间坐标，配合后处理软件，进行各种测绘、分析、仿真工作。介绍了三维激光扫描技术的原理，对目前的主要激光扫描硬件进行了比较，最后介绍了三维激光扫描技术在岩土工程应用的主要两个方面：边坡变形监测与岩石裂隙面勘察。相比常规监测和地质调查技术，三维激光扫描技术具有高精度、速度快、节省人工的优势，具有较大的应用潜力。

3D laser scanning and its application to geotechnical engineering

Ground-based 3D laser scanning is a relatively new data collection and analysis technique, which can scan the object quickly and acquire the high resolution, high density 3D coordinates of points. The 3D laser scanning technology and the principle of new scanning are introduced; and the main 3D scanning equipments are compared. 3D laser scanning technique can be applied to slope stability monitoring and rock fracture faces survey. Compared with the technology of traditional geotechnical monitor and geology survey, the 3D laser scanning technique has the advantages of high accuracy, high speed and low cost of human resources; and it has great potential for future application.
