STRESS RATIO EFFECTS ON COLLAPSE OF COMPACTED CLAYEY SAND

The paper summarizes the results of a multidimensional experimental research program, conducted to examine the relationships among principal total stresses and magnitudes of wetting-induced total, axial, and radial volume changes. A double triaxial test procedure similar to the double oedometer test was developed to determine the wetting induced collapse potential of soils subjected to anisotropic stress states. This test permits prediction of wetting induced volume change at a wide range of axial stresses using standard triaxial equipment and only two samples of each axial to radial stress ratio with less effort than required to obtain the same results from soaked-after-loading triaxial volume-change tests. Findings from the study are presented and discussed.
