Abstract
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.
