Coupled calculation model for anchoring force loss in a slope reinforced by a frame beam and anchor cables

Structures consisting of anchor cables and frame beams are structurally safe and reliable and are widely used in slope support engineering. However, the loss of anchoring force of the anchor cables is also very common, and this phenomenon directly affects the reinforcement effect of the anchoring structure. To predict the law and degree of the anchoring force loss accurately, a new coupled calculation model is established in this work. This new model is especially suitable for slopes reinforced with frame beams and anchor cables, and its accuracy is verified with on-site monitoring tests. The primary application of this new model is to provide theoretical guidance for late reinforcements of the anchoring forces of cables, which has great significance for safe operation in slope engineering.
