| 摘 要： | 尺寸效应是岩体结构面力学行为的重要特征。本文列举了结构面力学行为中普遍存在的尺寸效应现象,并由实测统计资料的分析,论证了结构面力学行为的尺寸效应具有分形结构。通过结构面力学行为尺寸效应的机理研究,建立了结构面力学行为尺寸效应分维数和结构面粗糙度系数尺寸效应分维数之间的相关关系,从而简化了结构面力学行为尺寸效应规律的表述,为客观评价岩体结构面力学参数提供最为有效的手段。

| Abstract: | Scale effects are one of the main characteristics of mechanical behaviour of rock joints. After analysis of the statistics obtained from observation, we take mechanical behaviour scale effects as a fractal body. By studying the mechanism of scale effects, we can set up the relationship between the fractal dimension of mechanical behaviour scale effect and that of joint roughness coefficients, therefore simplifying the scale effect law of the mechanical behaviour and providing an effective method for evaluation of mechanical parameters of rock joints. |
