Abstract

Slope stability is one of the key engineering problems in the whole lifetime of landfills. In this paper, combined with the wedge limit equilibrium analysis, a landfill stability analysis method based on the actual failure surface is proposed, and the model is verified according to the data of centrifuge model tests. It is found that this method can more accurately calculate the factor of safety (FS) of the slope of the landfill and evaluate the stability of the slope. Finally, sensitivity analysis was conducted to evaluate the effects of the actual failure surface angle, water level, soil parameters, and the presence or absence of a dam on the factor of safety.
