Slope stability analysis and optimal slope angle study of a construction granite mine
Take a construction granite mine slope as the research object,according to the mining status quo,engineering geological conditions to select the slope stability calculation profile,through the triaxial compression strength test to obtain the physical and mechanical parameters of the rock body,using the M-P method and Bishop in the self-weight+groundwater+blasting vibration loading conditions to calculate the stability coefficients of the status slopes and the design of slopes,and ultimately the final slope angle to take 1° down and 2° for the optimiza-tion of the slope angle.Calculation results show that:the local stability coefficient of the current slope of the mine does not meet the requirements,and the overall slope angle of the quarry slope can be optimized from 47° to 47.5°,and the optimized stability coefficient meets the requirements.
