摘要	Based on the FLAC3D software, try to establish overall length grouted bolt anchorage bedding rock slope numerical analysis model by amendatory cable unit, and to improve shear stress extraction method. Shearing and evolution of bolt-mortar and mortar-rock interface are simulated and analyzed, respectively. The study found that the mortar-rock interface shear stress is far less than the bolt-mortar interface, and the distribution of shear stress is very uneven on both sides of the anchor neutral point. The shear stress near neutral point is large and the shear stress on bolt ends is small. Not only the amplitude and frequency of seismic wave has a great influence on the shear stress distribution of slope anchorage interface, but also the shear stress of slope anchorage interface increases with the increasement of seismic wave duration. The length of bolt also has a great influence on the shear stress distribution of slope anchorage interface, but the influence of anchor angle is smaller. For the first time, the shear stress distribution at the anchorage interface under earthquake is obtained, and the influence of ground motion parameters and anchorage modes on the distribution of shear stress is revealed. The study provides an reference for the design and construction of side slope anchorage. © 2019, Nanjing Univ. of Aeronautics an Astronautics. All right reserved.
