【摘要】 岩体结构面的表面形态直接控制着结构面的抗剪强度。为了准确地描述岩体结构面的表面形态 ,介绍了一种用来描述结构面表面形态的方法三棱锥曲面分维法。并将其应用于西南地区某水电站坝区发育的层间错动带表面形态的研究 ,并由曲面分维值计算获得了结构面的起伏角。计算结果与野外观察到的总体宏观规律吻合 ,表明利用三棱锥曲面分维法来求得结构面的表面分维 ,近而获得起伏角有一定的可信度。更多还原

【Abstract】 The configuration of structure controls the shear strength of structure surface, so it is very important for geological engineers to describe the structure’s configuration correctly. The Triptych Surface Fractal is introduced, and also applied to the interlayer fractures in a dam site in Southwest China, the wavilness angles of these fractures are also calculated. The angles calculated agree with what observed in field, this shows that application of Triptych Surface Fractal to get wavilness angles is credible.更多还原
