STUDY OF COMBINED EVALUATION METHOD FOR SAFETY OF OPEN-PIT SLOPE AND ENVIRONMENT
露天边坡与周边环境安全综合评价方法的研究

The stiffness resisting deformation and strength resisting failure induced by open-pit excavation are two problems. Therefore,different influence mechanisms are produced. Slope rockmass is safe if the strength condition is satisfactory. But,surrounding environment will be broken if stiffness is not sufficient. In the light of old mining area surrounding city,the safety definition should assure mining and environment safe. Otherwise,economical benefit may be a negative value. The analysis is made on these problems. Then,synthetic analysis on slope stability and ground deformation combined history-case is carried out and corresponding analytical methods are given.
