Comparison of deterministic, probabilistic, and rock mass classification methods of slope stability analysis at Bald Mountain Mine, Nevada.

摘要

The stability of the pit walls at Bald Mountain Mine, Nevada were evaluated. Both deterministic and probabilistic analyses were performed on the slopes, which were found to have a high potential of failure. Even though both methods are useful in slope design, the probabilistic slope stability analysis provides a better indication of the inherent risk of failure.;The feasibility of using rock mass classification systems for rock slope evaluation was also assessed. This study found that these systems can be adapted for use as a field observation method of rock slope analysis.
