A granular material with angular particles compacted on the dry side of optimum can form a structure which is capable of significant further densification, but the classic collapsible soils are natural materials where the combination of particle type and sedimentatio

The basic five types that need to be recognised are (related to the R-size diagram, see Figure 1) AA’ active clay minerals, BB’ inactive clay minerals, C fine cohesive primary minerals, D silt (at R approximately equals 1), E sand.

The K. values are consistent with compression of a laterally confined solid having a low Poisson’s ratio..At the site farther from the loess source, the stress path inclines upward at 45., indicating that lateral st

In addition, multi-spectral methods derived from remote sensing are now being used in microfabric studies to subdivide images into size or mineral g

Field examples of collapse are presented to emphasize the practical importance of collapse studies. Collapses are classified from the micromechanical point of view as collapses by debonding, by grain crushing, by fabric transition and by
