Abstract

At present, a variety of slope stability assessment methods based on rock mass quality classification have been proposed. However, the rather mature evaluation system for different types of rock slopes is still absent. In this paper, the existing classification methods for rock slope are first discussed, then by combining the Qslope and BQ methods based on the relationship between different classification systems, a relatively simple and applicable evaluation system is proposed, which uses the BQ method to obtain the basic quality of the rock slope and then the Qslope method to revise this rating according to the geological environment of the slope. The new system can reduce field survey and subjective factors. The case study shows that the evaluation results of the rock slope using the new method coincide with the actual stability status, showing that this method can be further tested in engineering practice.
