摘要
There are many soft-hard interbed slopes in Three Gorge Reservoir and their deformation is complex. The factor causing the plastic flowing-cracking slope deforming is thicker soft rock basis, such as Fuling-Yanshang dangerous rockmass. The factor causing creeping compressing-cracking slope deforming is weak seam, such as Yunyang Yunjiang cutting slope for example. By stress analysis, these tow type modes of rockmass failure were analyzed, the former is rock extense cracking, the later is compressing crack. These results could help understanding of the single gentle bedding soft-hard interbed slope deforming.
