Abstract: In light of the engineering geological conditions of F9 sliding mass of the east high steep open-pit slope in Daye Iron Mine, the tress and strain conditions of F9 sliding mass in the slope excavation process are simulated and analyzed using finite element software. Back analysis is made on the mechanical parameters of this sliding mass according to the site monitoring on its deformation, from which its mechanic parameters C and φ values are found, providing the reference for analysis of the slope stability.
