A REVIEW ON STATE-OF-THE-ART ANALYSIS OF ROCK SLOPE STABILITY AND PRESTRESSING ANCHOR

In this paper, firstly, the main characteristics of currently used analysis methods of rock slope stability are reviewed, which can be classified into two categories: a) The qualitative analysis methods, such as nature-history-geology analysis method, engineering geology analog method, graphic interpretation, expert system etc.; b) The quantitative analysis methods including: a. deterministic model methods, such as limiting equilirium method, stress-strain analysis method; b. Undeterministic model method, such as reliability analysis method, gray system theory method and fuzzy-synthetic evaluation; and c. rendom finite element method which is the combination of deterministic and undeterministic methods. Secondly, the design and stability analysis ofprestressing anchored rock slope are elaborated.
