Abstract

Limit equilibrium method is still mainly adopted in the slope design,with the reason of its simple mechanism and convenient modeling;the deepening slope in Yingpin II pit is chosen as the engineering background.The simplified Bishop method of limit equilibrium method is adopted to analyze slope stability,which shows that safety factor of slope is 1.443,the slope is in the stable state;the slip surface is in the upper part of slope,which does not run through the whole slope,so the slippage place can be reinforced by some certain methods.
