Abstract: This paper presents a case history of applying envelop design approach for the evaluation of a potentially unstable W7 rock mass in Jiazhou, Tongren. Various failure modes are analyzed and the stability of the rock mass are evaluated with reliable and matured rock mechanics and structural mechanics methods. The mitigation design was based on the analysis results. After five years of operation, it is proved that the stability design and mitigation are reasonable.

Key words: Unstable Rock Mass, Failure Modes, Stability Evaluation, Mitigation Design
