Abstract

The SRS method explicitly relates the coefficient of consolidation c v and end of primary (EOP) settlement δ p to the intercept and slope of the linear section of the observed d δ t /d t – δ t curve that can theoretically be recognized for the average degree of consolidation U ≥ 52.6%. The SRS method calculates the coefficient of consolidation independently of any specific value of U and can simultaneously compute the EOP settlement δ p without the need to continue the test into the secondary compression range. Thus, the overall testing time may significantly be reduced and the influence of load duration as well as secondary compression may be minimized. Results of oedometer tests on four clayey soils are used to compare the SRS method with existing methods such as the Casagrande and Taylor methods.
