Determination of Coefficient of Consolidation ( ) for Large Strain and Variable Values


Mikasa's advanced consolidation theory and Mikasa's method of determining cv from the oedometer test are discussed. The latter consists of a curve rule method and correction of cv by primary consolidation ratio, r. Theoretical time-consolidation relationships are shown for the cases of finite strain both with and without cv change as the relation between time factor, Tv, and degree of consolidation in terms of settlement, Us.

Examples on a clay and a peat show that the standard procedure of cv determination using the curve rule method and correction by r gives practically the same f-cv relationship as does the procedure based on the advanced consolidation theory, though a better curve fitting is always obtained by the latter.

Advanced consolidation theory, however, is necessary to interpret the physical meaning of consolidation test results and also to make a settlement prediction in the field.
