Abstract

Slope stability analysis is of great significance for ensuring engineering safety and preventing natural disasters. Taking a certain road engineering project as an example, this paper combines rock strength indicators and finite element method to analyze the stability of the slope. Firstly, the rock strength parameters and geotechnical parameters were obtained through field investigation and laboratory experiments. Secondly, the finite element model of the slope was established using PFC3D software, and stability analysis was carried out. Finally, the factors affecting the stability of the slope were discussed, and corresponding reinforcement measures were proposed. The research results show that rock strength indicators and finite element method are effective methods for slope stability analysis, which can provide reasonable engineering decisions.
