ABSTRACT: The existence of loose landslides not only poses a huge safety hazard to the
construction of tunnel entrances, but also significantly increases the difficulty
of site construction. In this paper, we investigate the comprehensive slope reinforcement management technology for tunnel entrances
in thick landslide strata, using the finite element analysis software ABAQUS
to study the slope safety coefficients, displacements and plastic zone changes under
different management conditions, propose a design structure for slope stability
enhancement in thick landslide strata, and analyse the effect of the application
of slope stability enhancement measures for thick landslide strata. The results
show that the enhanced design structure is used to enhance slope stability. The
results show that after the landslide treatment with the enhanced design structure,
the slope safety factor was increased from 0.961 to 1.512, the maximum horizontal
tangential displacement was reduced from 330.2 mm to 32.74 mm, and the area of plastic
zone was significantly reduced, and the landslide support effect was remarkable.
