Formatted abstract

Secondary Compression of soft clays is a crucial issue in regard to construction applications where currently no accurate method for accommodating this form of settlement in design is known. Odometer tests and soil classification tests were conducted to accurately classify the samples used and to assess the characteristics exhibited when secondary compression is observed. Secondary Compression was investigated within this research in two segments. Initially the applicability of empirical equations that predict the magnitude of secondary compression were assessed against test data obtained. This was done to ascertain the degree of accuracy that could be expected from the equations presented. Secondly, the effectiveness of surcharging a clay in the aim of reducing secondary compression was investigated. It was shown that a reduction in the rate of secondary compression could be observed for a surcharge that induced an overconsolidation ratio of 1.1 or more.
