| Based on the finite element limit equilibrium method, the influences of slope morphology(slope ratio, slope height, slope ratio of upper slope)on crack depth, the most prone location of the crack and the safety factor of the slope are analyzed. When the upper part of the slope is horizontal and the slope ratio is constant, with the increase of the slope height, the slope shoulder crack depth of the slope gradually increases, and the safety factor of the slope gradually decreases. When the upper part of the slope is inclined and the height of the slope is constant, the slower the upper part of the slope is, the smaller the crack depth of the shoulder is. The closer the crack location of slope shoulder is to the slope back, the greater the safety factor of slope body will be. When the upper slope ratio of the slope is constant, the higher the slope, the greater the crack depth of the shoulder. The farther the crack location of shoulder is from the slope edge, the smaller the safety factor of slope is. |
