英文摘要This paper studied the dynamic response and failure characteristics of the anti-dip rock slope through a large-scale shaking table test. An anti-dip rock slope model with a length of 2.2 m, width of 0.8 m and height of 1.6 m has been constructed in a rigid model box. The similarity law and dimensional analysis have been applied to determine similarity relations and loading conditions. The results indicated that the acceleration was amplified with the increase of the model elevation and shaking intensity. The upper slope showed an exceedingly strong response to horizontal acceleration, meanwhile the lower part showed a stronger response to vertical acceleration. Both the horizontal and vertical accelerations sharply increased at shallow depths of the slope surface. Rock mass dislocations occurred at the slope crest during the initial deformation stage, and subsequently downward toppling took place at the slope crest. Tensile-shear cracks presented in upper slope and went through the model blocks, and intense acceleration responses were recorded where the rock mass was severely deformed. Finally a curved-linear sliding surface was formed. It is notable that shallow landslide was not accidental phenomenon in the lab experiment.
