In this study, two-dimensional model loading tests were carried out to analyze the problem of the bearing capacity evaluation in the early stage of ground improvement in marine clay dredged deposits. The bearing capacity was estimated using previously proposed methods for double-layered clay deposit, that is, Button’s (1953), and Brown & Meyerhof’s equation (1969). To estimate the application of these equations, the estimated bearing capacity was then compared with the results of the two-dimensional model loading tests.
