Abstract
The oedometers used for one-dimensional consolidation tests are proportioned such that their height-to-diameter ratio lies in the range 0.17–0.40. Sometimes, it is desirable to test a soil specimen that has a significantly larger height-to-diameter ratio, where the wall friction must be considered in the analysis. Such tall oedometers can become useful tools in consolidation tests, if the wall friction can be accounted for rationally. The objective of this paper is to develop some theoretical basis for analyzing consolidation test data from tests carried out in tall oedometers. It is shown that the same average degree of consolidation versus time factor charts can be used for height-to-diameter ratios as much as 3, provided the specimen is doubly drained. Consolidation tests carried out in the standard oedometer and tall oedometer in the laboratory gave very similar values of coefficients of consolidation.
