| 摘 要： | 岩体结构面几何参数传统获取方法是使用地质罗盘和直尺进行现场获取,但是该方法存在效率低、难度大等问题,为了有效解决该问题,本文引入三维激光扫描技术到岩体结构面几何参数获取中,大幅提高了岩体结构面几何参数获取的效率。为了验证该技术的有效性,选择国内某矿山边坡进行现场扫描,对扫描获取的点云数据进行预处理后,利用结构面识别和分组方法,快速地提取了岩体结构面并统计了结构面的倾向、倾角、迹长等信息,为后续边坡稳定性计算提供了有效的结构面几何参数。

| Abstract: | traditional method for geometric parameters of rock mass structural plane is using geological compass and straightedge scene, but this method has such problems as low efficiency, big difficulty, in order to effectively solve the problem, this paper introduced 3d laser scanning technology to obtain the geometric parameters of rock mass structural plane, greatly improves the efficiency of obtaining geometric parameters of rock mass structural plane. In order to verify the effectiveness of the proposed technique, choose a domestic mining slope to get point cloud data which will be preprocessed by the mean of denoising and hole repairing method, then use the method of structural plane recognition and grouping to quickly extract the rock mass structural plane and statistical structure information such as the orientation, obliquity, trace length, it will provides effective structural plane geometric parameters to slope stability calculation. |
