| Research Abstract |
(1) The minimum void ratio after volumetricshrinkage (absolute dry condition) is almost the same for every kind of soil, if the size, vacuum pressure and initial water content of soil specimen differ from each other.
(2) Shrinkage and desaturation characteristics of reconstituted cohesive soil can be formulized in two straight lines, respectively. A required parameter is only e_min or w_sand the compatibility with test results is high
(3) The relation of w-V/V0in initial water content w_0>w_p(w_p: plastic limit), Sr, and e can be approximated in linear for every initial water content. In w_0
