but positive at stress levels 100, 200 and 400 kPa’s. Analyzing
these results, it can be argued that, the mechanism of
consolidation changes around 100 kPa stress range which is
realized as the change of sign of the correlation found between
ψ
/v and PF. This finding complies with the argument put
forward by McConnachie (1974) who pointed out the
possibility of occurrence of a fundamental change in the
mechanism of consolidation between the pressures 10 and 100
kPa. The results summarized here are part of an ongoing
research. Further evidence is expected as the results of the new
tests are released.
