When the variation of secondary compression, with log(10) t is non-lin
ear, the quantification of secondary settlement through the coefficien
t of secondary compression, C-alpha epsilon, becomes difficult which f
requently leads to an underestimate of the settlement, Log(10) delta -
log(10) t representation of such true-compression data has the distin
ct advantage of exhibiting linear secondary compression behaviour over
an appreciably larger time span. The slope of the secondary compressi
on portion of the log(10) e - log(10) t curve expressed as Delta(log e
)/(log t) and called the 'secondary compression factor', m, proves to
be a better alternative to C-alpha epsilon and the prediction of secon
dary settlement is improved.
