Abstract: The objective of this paper is to research on application of S-shape curve equation to describe consolidation test results by using curve fitting tool based on analysis of factors of model including SSE, R-square, Adjusted R-square and RMSE. The consolidation test results are plotted properly and then three S-shape curve equations introduced by Brooks and Corey (1964), van Genuchten (1980) and Fredlund and Xing (1994) are used to fit the tested data, The goodness of fit is shown and finally the capability of application of S-shape curve equations is proposed. By testing with more than 30 samples together with applying curve fitting tool, the results show that Fredlund and Xing model is the most appropriate one to describe consolidation test results.
