ANALYSIS OF MECHANICAL BEHAVIOURS AND EFFECTS
OF PRESTRESSED ANCHORAGE |

Abstract Prestressed anchorage technique is an important method to reinforce high rock slope. Based on the numerical simulation analysis by using 3D finite element method，not only the mechanical characteristics of tendon force，shear stress and displacement among anchor cables and grouted body and rock mass but also the anchorage effectiveness are studied. In addition，the regularity of cables pitch is discussed. It is concluded that the structural properties of rock mass is the main factor affecting anchorage stress distribution. The suggested method could be widely used for practical engineering.
