- Abstract
- Rational methods for seismic slope stability analysis require the prediction of critical state displacement behavior of an embankment. The use of advanced plasticity models, which satisfy the requirements of continuity and uniqueness of solution and have the capability of simulating a wide range of real effects in soils, is essential in this type of analysis. The focus of the research was the development of a simplified cap type plasticity model specialized for seismic analysis of embankments. The specific objectives that were met are: (1) the incorporation of a viscoelastic stress-strain relation into the cap model to simulate cyclic hysteresis below the yield surface, and (2) the incorporation of simplifying assumptions into the model in order to reduce the number of parameters necessary to fit the model to properties which can be obtained from data most typically available to geotechnical engineers.
