Abstract:
Slope stability can be affected by many factors. Unstable failure of slope in open-pit to underground mining commonly appears in toe of slope with larger plastic zone. This paper introduces a new type of support method in high slope-supporting structure of anchor retaining wall at toe of slope. Retaining wall is designed mainly for the areas entering previously into plastic zone. In order to improve the anti overturning ability of retaining wall, artificial boundary pillar is connected with the wall at the bottom of slope by bolts. The comparative analysis of the numerical simulation shows that anchor retaining wall at toe of slope raises the stability at the toe and the stability factor of slope to some extent.
