Limiting Compression Curves

摘要

Depending upon the initial water content of the soil sample, a family of compression curves is possible. Identification of characteristic limiting water contents for any fine grained soil sys- tem, along with the unique mechanisms controlling them, helps ob- lain the limiting compression curves. In the present note, it has been demonstrated that the compression curve obtained with its origin at the free swell limit of the soil represents the global upper bound compression curve, and that the compression curve obtained after the still has reached equilibrium under cyclic consolidation repro- sents the global lower bound compression curve.
