Abstract

Abstract: In order to ensure the safety of tunnel construction, a retaining structure is needed to control landslides and reinforce tunnels in slope failure areas. Numerical simulation is used to study the interaction mechanism between tunnel excavation and slope displacement under the reinforcement of the "upper retaining" anti-slide pile. The results show that: the "upper retaining type" anti-slide pile as the supporting structure has a significant effect on the control of tunnel deformation in the slope failure section; the displacement deformation of the tunnel vault is consistent with that of the anti-slide pile, which indicates that the anti-slide pile retaining structure based on the "tunnel landslide system" can significantly improve the stress of the tunnel structure and is conducive to the safety of the tunnel structure and stability of the slope.
