Research on Dynamic Response of Full-length Adhesive Anchor Cable Under Seismic Action
Full-length adhesive prestressed anchor cables are currently the most common reinforcement measure for slope support,but the mechanism and laws of their support and dynamic response under seismic loading are not yet clear.Aiming at this problem,a numerical simulation model was established based on the centrifugal model test to research the dynamic response characteristics of full-length adhesive anchor cable in detail.The model was established by taking into account the dimensions,boundary conditions,and dynamic input characteristics.Through the comparison and analysis of numerical simulation results and centrifugal model test results,the deformation and stress response characteristics and laws of anchor cables at different positions of the anchored slope and different parts of the anchor cable under the action of seismic acceleration were expounded.The anti-sliding mechanism and dynamic response law of the full-length cohesive prestressed anchor cable under dynamic conditions were further revealed.The research results have important reference value for the prestressed anchor cable reinforcement of high seismic intensity slope and the safety evaluation of full-length adhesive prestressed anchor cable under seismic conditions.
