Under the Osaka bay area, there exist 13 marine clayey strata which are numbered as Mal3(the shallowest) to MaO(the deepest) In the case of general buildings the compressibility of the Mal3 is often taken into account for settlement problems But for the case of great or heavy buildings, not only the Mal3 but also other strata should be considered for settlement problems Thus it is important to obtain the compressibility for general reclaimed area, where consolidation test using the soil samples in general has to be carried out including extracting undisturbed soil samples that requires much labor and expense This test includes extracting undisturbed soil samples requires much labor and expense Instead of the complicated consolidation test, in this paper a formula for compressibility has been presented using simple test by undisturbed samples that only relates with void-ratio and effective pressure Using the soil samples around Kansai airport island, the compressibility have been obtained statistically The results from the formula and from the test are nearly same, which clearly indicates that the formula is suitable for simple settlement predications.
