The purpose of this paper is to investigate the change of soil property each depth through the large consolidation test. In addition, we compared and analyzed results of the standard consolidation test with these of the large consolidation with test loading 0.4kgf/㎠ for 30 days. After consolidation, we performed soil test(water content, direct shear test, coefficient of permeability and others) at each depth. The soil test meet with different results at each death. At the surface, strength and unit weight are the largest but coefficient of permeability, void ratio and water content are the smallest. Specially, in the case of coefficient of permeability, it is affect coefficient of consolidation, which is need to take more accuracy study. In this case compression and drain well, the difference of soil property is small about depth. After Cc, Cv were found by Back-analysis, if that is apply to standard consolidation and large consolidation test, the results are similar to curve of measurement settlement, but it is different to Cc, Cv of consolidation, also it is need to take added study. A thesis submitted to the Committee of the Graduate School of Industrial Science, Gyeongsang National University in partial fulfillment of the requirements for the degree of Master of Science in March 2004.
