Reinforcement mechanism analysis of lattice beam and prestressed anchor rod system for loess slope

Lattice beam and prestressed anchor rod are used to enhance stability prevent failure of soil or rock slopes. In this study, a model (LBPAR) system was designed with reinforcement mechanisms test constructed circular slip surface loess slope. First, interaction between the slope LBPAR investigated by an analysis model. Stability sliding mass from bed arc-shaped then studied experimental designed. Finally, internal force distribution lattice beams in using large-scale physical test. The results were compared those calculated reverse method, indicating that strengthened space improved overall With vertical loading, axial tensile stress main increases continuously. bending area concentrated within 2 m surface. And maximum moment reaches 70 N·m. subject load pressure, beams’ dead weight meantime earth pressure value is near node beams. It proved such method excels engineering design landslides, which has promising applications future.
