초록
In this study a series of in-situ and laboratory tests such as SPT, CPT, DMT and oedometer test are performed and then the stress history of soft ground is evaluated from the different method for estimating preconsolidation pressure. Casagrande method(1936), which is generally used in the conventional design, overestimates to the known preconsolidation pressure but Becker method(1987) similarly estimates to the known values. Also the results of DMT is similar to that of Becker method, and SPT and CPT overestimates the stress history of investigated ground.
