摘要
从分形几何的观点出发，根据结构面具有统计自相似特征，用Ｋｏｃｈ曲线在聚碳酸脂板上加工出不同粗糙度的结构面模型。对试件做了一系列单向压缩和压剪光弹实验，应用光弹理论分析了结构面在压剪载荷作用下应力场分布变化规律。结果表明。
Based on the fractal geometry viewpoints and good selfsimilarity of structure surface, Koch curves are used to model the structure surface with different roughness, which construct a model made with polyvinyl carbonic. A series of uniaxial compression and compressionshear photoelastic experiments are carried out for photoelastic samples. The variation of stress field on structure surface is studied with photoelasticity theory. The results show that normal pressure has an important influence on the strength of rock structure surface with different roughness.
