摘要： 高边坡危岩体传统调查难度大，危险性高，三维激光扫描技术的高效率、高精度、远距离非接触测量等优势弥补了传统地质勘察方法的缺点。利用三维激光扫描技术可优化传统地质调查过程，且室内数据处理软件技术成熟，可实现对危岩体的定量分析，如:危岩体几何尺寸测量，高精度危岩剖面图，结构面产状、迹长、连通率、间距等测量，危岩体三维坐标精确获取及危岩体边界范围准确界定等;另外，通过三维激光扫描技术后处理软件的二次开发，并对建立信息化危岩稳定性评价系统进行初步研究，从理论上论证了其可行性。由此可见，三维激光扫描技术在高边坡危岩体调查中具有较高的应用价值与广阔前景。

Abstract: Traditional approach of investigating high slope perilous rock is very difficult and dangerous. Three-dimensional laser scanning with high efficiency, high accuracy and remote non-contact measurement makes up the deficiencies of traditional geological investigation methods. By 3-D laser scanning, traditional geological investigation process can be optimized. Moreover, with the development of indoor data processing softwares, quantitative analysis on perilous rocks can be conducted, for instance, the measurement of geometric dimension of perilous rock, highly accurate real tangent geologic profile, measurement of structural plane occurrence, trace length, connectivity rate and spacing, as well as the acquisition of space coordinate and the determining of perilous rock body boundary. In addition, by redeveloping post processing software for 3-D laser scanning and establishing rock stability assessment system, the feasibility has been proved in theory. Thus it can be seen, 3-D laser scanning has broad application and prospect in geological exploration.

Key words: perilous rockmass, high slope, 3-D laser scanning, diversified application
