Centrifuge Model Test on Anti-dip Rock Slopes with Unequal Thicknesses Subjected to Flexural Toppling Failure
Flexural toppling failure of anti-dip rock slopes (ADRSs) with layers of equal thicknesses has been investigated by many researchers, however, in natural slopes, rock layers in ADRSs are often of unequal thicknesses. To analyze this condition, six slope models were manufactured with glass plates and tests were conducted in a geotechnical drum centrifuge. In these experiments, deformation and interlayer force characteristics were obtained with cameras and film pressure sensors. The centrifuge test results show that the failure process can be divided into three stages: failure of the slope toe, development of fractures and failure of the slope. Initial toe failure has little effect on the stability of the upper rock mass. Through centrifuge test results, it is determined that slopes with only thick layers therein can be used in the evaluation of the stability of slopes with layers of unequal thicknesses. This is because thicker strata have a greater bending stiffness and bending strength than thin strata, thus influencing slope deformation and stability.
