| Abstract: | Based on the rheological stress-strain relationship of soil, the characteristics of the s～t curve of an embankment are analyzed under instant loading, linear or approximately linear loading and multi-stage loading. A prediction model for settlement under the above-mentioned three loading sequences is then developed. The case studies verify the applicability of this model. |
