Abstract The shear strength characteristics and the wearing mechanism of rock joints in the shear process are very important for analyzing the stability of rock mass. 3D laser scanning and numerical controlled engraving were used to produce the natural joints in the specimens of sandstone，marble and granite. The point cloud registration and the fidelity rate test were carried out based on the standard ICP algorithm of four elements. The direct shear tests with acoustic emission monitoring to three kinds of natural rock joints under different normal stresses were carried out. The overlapping of the point cloud data of rock joints before and after shear test was realized with the algorithm of point cloud registration. The wearing characteristics of natural joints were analyzed. The experimental results show that the natural rock joints produced by engraving are of high accuracy and lead to consistent results. Based on the AE characteristics，the shear process can be divided into three stages：I-frictional sliding stage，II-shearing and gnawing stage，and III-residual friction stage. Comparison of the 2D and 3D morphology before and after the shear tests show that the front slope slides，the inhomogeneous wearing damage and local gnawing of the convex point occur on meso-scale，and the local and inhomogeneous failure zones occur on macro-scale.

Key words： rock mechanics natural rock joints numerical servo engraving shear damage direct shear test
