Analysis of a New Flexible Hinged Frame Anchoring System

Abstract:

By adopting a hinged form at the bearing joints of the traditional framework anchoring systems, a new overall flexible slope supporting system—hinged framework anchoring system was established. The system can not only keep anchoring force transmission mechanism to ensure the overall slope reinforcing effect, but also allow the slope to have finite deformation to dissipate energy (under dynamic mechanism). A flexible hinged frame anchored theoretical model is established and solved based on finite difference program FLAC3D. Strength reduction technique is used to evaluate the slope stability and obtain the factor of safety. By the comparative analysis of rigid frame connected supporting system, internal force and deformation of each component part of different supporting system are compared. The results showed that: the flexible framework anchoring system can effectively control the slope sliding to ensure the slope stability. At the same time, the flexible supporting system had obvious advantages of improving its stress states compared to the traditional framework anchoring system. With a new framework for anchoring flexible hinge supporting system was proposed and analyzed, a new design idea in slope reinforcement is provided, while a basis for the application of the new supporting system is provided.
