 the lattice beam and pre-stressed anchor rod, LBPAR, system is a new approach for enhancing the stability and preventing failure of soil or rock slopes. This study examined the interaction between the loss slope and the LBPAR system, as well as the stability of the sliding mass from the sliding bed with an arc-shaped sliding surface. Additionally, the internal force distribution of lattice beams in the LBPAR system was investigated through a large-scale physical model test. The result showed that the LBPAR system strengthens the sliding mass in space and improves the overall stability of the loss slope. Furthermore, it was found that the vertical loading of the main anchor rod increased continuously, while the bending area of the anchor rod was concentrated within two meters of the sliding surface. Finally, the maximum bending moment reached 70 Nm, indicating that the LBPAR system can effectively reduce the risk of slope instability.
