摘　　要：通过模拟试验对岩石结构面抗剪强度方向性的假设做了验证,证明了具有不对称性的结构面其抗剪强度都会表现出一定的方向性。发现这种抗剪强度方向性与尺码法测得的结构面分形曲线中上升(正坡)步数占总步数的百分比有关,也与结构面表面的最大起伏度有关。The standpoint （hypothesis） that the orientation of shear strength of rock structure face was proved by simulation tests. In the tests it was found that the shear strength is different when shearing a rock along a joint with asymmetrical profiles in different orientation, the orientation of shear strength is relative to the percentage of upward steps （ upward slop） to total steps in fractal curve of rock structure face, which was measured by yard -stick method and the most undulate degree of rock structure face.
