Abstract

 This paper aims at clarifying the deformation-strength properties for coastal soft cliff. A series of triaxial compression tests was performed on undisturbed specimens sampled from the coastal soft cliff in Hokkaido, Japan to obtain mechanical properties such as shear strength. From the triaxial test results, it was found that the effect of fabric anisotropy on the strength-deformation behavior could not be ignored for the coastal soft cliff. In addition to these laboratory tests, a series of 1G-model and centrifuge test to grasp the feature of slope failure due to wave erosion was conducted on the model cliff having the corresponding strength with that of the soft cliff. Based on the test results, a slope stability evaluation was discussed in detail.
