Differential settlement is serious problem in reclaiming a wide tract from the sea. As a primary factor, spatial variation of soil profiles can be considered. In estimating spatial variation of soil profiles, “Kriging” can be available. However, practical Kriging have not been established enough. Object of this study is to establish practical Kriging estimating spatial variation of soil profiles using over 400 standard consolidation test results for a submarine clayey deposit. In this paper, we examine that the effect of evaluation of uniformly random component of soil profiles and anisotropy correlation on the degree of estimating accuracy.
