Numerical Analysis on the Slope Stability of the Multi-Step Waste Rocks Dump with Retaining Wall

Abstract:

In recent years, with the rapid development of highway, high-speed railway and other large cross-section tunnel engineering, a large number of waste rocks are piled up and induce various security issues which affect people's production and living environment seriously. The actual capacity of the LQS tunnel waste rocks dump has been far more than its design dimensions, and brings about a certain extent potential safety hazard to some expressway projects in Sichuan Province. Utilizing FLAC3D and its Mohr-Coulomb criterion establish 2D model, and analyzes displacements, and calculate its safety factor, estimate the slope stability and destructiveness of the waste rocks dump. The calculation results are coincide with the actual damage situation well. In order to improve the slope stability of LQS tunnel waste rocks dump, the influence degree of its wall height, moisture ratio, and slope ratio of safety factor will be analyzed, sequentially confirm the critical value of every factor, and find out the prominent factors. The numerical analysis on the slope stability of multi-step waste rocks dump with retaining wall will be the basis of similar sites.
