Strength loss and strain softening/localization are important issues for sensitive clay slopes. There is a question that if the ground moves a fraction of a meter due to earthquake shaking, sensitive clays would be just as easily remolded and trigger a catastrophic failure. Two possible reasons why we expect different relationships between deformation and strength loss are: seismic (dynamic) failure mechanisms are different from gravity driven (static) failure mechanisms, and rate dependent shear strength hinders localization of deformations into distinct shear planes. |
