Characterization of mechanisms contributing to distribution of yield stress in a soil profile (on the basis on Jamiolkowski et al. (1985)).
| A) Mechanical One-Dimensional | 1) Changes in total vertical stress (overburden, glaciers, etc.) |
Uniform with constant s’p-s’v0 (except with seepage) |
| B) Desiccation | 1) Drying due to evaporation vegetation, etc. |
Often highly erratic |
| C) Drained Creep (Aging) | 1) Long-term secondary compression | Uniform with constant s’p/s’v0 |
| D) Physicochemical | 1) Natural cementation due to carbonates, silica, etc. |
Not uniform |
