Abstract:: Anchor rope spacing is the key parameter on the design of slope anchor. Because the formation of potential failure surface in the cataclastic rock slope is under the control of the inner main crack, fracture mechanics theory is introduced in this paper in order to determine the anchor rope spacing of the fractured rock cutting slope. By analyzing the crack tip stress field and concerning with the security requirements of slope design, this paper brings forward the analysis method of this type of anchor spacing based on the fracture mechanics theory, and the reliability of the method is verified through practical engineering application.
