| 摘 要： | 利用高精度三维表面形貌测试仪Talysurf CLI 2000对节理试件表面进行扫描，将表面粗糙形状进行数值化表达并实现节理面的三维可视化。在此基础上，运用分形几何理论对节理表面三维形貌特征进行分析，得出节理剖面线的分形维数与JRC之间的函数表达式。以单个节理面为研究对象，探究节理表面分形维数与剖面线分形维数以及JRC之间的关系，这对分形几何理论在节理表面形态研究中的深入应用有重要意义。

| Abstract: | The surface of joint specimen has been scanned by using 3D surface profiler Talysurf CLI 2000 and the surface shape is numerical expressed in order to implement the 3D visualization of joint surface. Then，after the analysis of 3D surface topography characteristics with fractal geometric theory，the function，connected with fractal dimension and JRC of joint profile，is put forward. By taking a single joint surface as the research object，this paper probes into the relation between the fractal dimension of joint profile，JRC and the fractal dimension of joint surface，which has important significance in introducing fractal geometric theory to research the joint surface state. |
