Research Abstract |
The failure process and mechanism of a bedding plane resulting from an earthquake-induced landslide have been not understood. This study aimed for clarifying dynamic behavior and strength property of specimen having a strength discontinuous plane such as bedding plane. The developed cyclic loading ring shear tests were carried out with mono layer specimens with either non-cemented or cemented samples, and with a laminated layer specimen consisting of non-cemented and cemented samples under a constant volume condition. The cyclic shear behavior and strength for these specimens to reach a failure state were examined based on the test results. As a result, the laminated layer specimen showed lower cyclic shear strength as compared with the other specimens.
