The consolidation stress ratio used were 0. 65, 0.8, 1.0 and the types of drainage were axial drainage and radial drainage. The results showed that in. the normally consolidated range the consolidation stress ratio has-no significant effect on the total compression. For the overconsolidated range the results were not clearly defined. In the normally consolidated range, a decrease in consolidation stress ratio causes an increase in the vertical compression. This causes the  coefficient of consolidation to decrease in axial draina.ge test but increase in radial drainage one. 0aSoil consolidation test 0aClayxThailandxBangkok1 aMoh, Za-Chieh, eChairperson1 aChai Muktabhant, eExamination Committee1 aNelson, John D., eExamination Committee2 aAustralian Government, eScholarship Donor2 aAsian Institute of Technology.tThesis ;vno. 381  3Full-Textuhttp://203.159.5.9/ait-thesis/detail.php?q=B24306
