摘要
岩体结构面粗糙度及其各向异性是岩体力学课程的重点和难点内容。该文采用数码相机对岩体结构面进行倾斜摄影测量,在Context Capture软件中建立结构面实景模型,采用Cloud Compare软件对三维实景模型进行剪切和点云简化;在MATLAB软件中获得不同剪切方向上的起伏曲线,进而确定各起伏曲线粗糙度系数,并评价其各向异性特征。将上述成果用于岩体力学课程的教学,直观、生动地展示了结构面粗糙特性,取得了良好效果。
The roughness and anisotropy of rock structural plane are the key and difficult contents of the rock mechanics course. The tilt photogrammetry of rock structural plane is carried out with digital camera, and the real scene model of structural plane is established in context capture software. The cloud compare software is used to carry out the shearing and point cloud simplification for the 3 D real scene model. In MATLAB software, the undulating curves in different shearing directions are obtained, and then the roughness coefficients of the undulating curves are determined, and the anisotropic characteristics are evaluated. When the above results are applied to the teaching of the rock mechanics course, the roughness characteristics of the structural plane are displayed intuitively and vividly, and good results are obtained.
