The Optimum Design of Slope Angle Based on Critical Sliding Field

The optimum design of final highwall is a multivariable and complex technical problem that every change in any factor will influence the stable state. Based on the history-case, this paper applied the critical sliding field to search the critical slip and evaluate the stability of slope with different geometric forms. Comprehensively compared the global and local slope stability and its economic benefits, finally achieved the optimum design of final highwall.
