Laboratory Experiment of the Rheological Property of Soft Clay and the Improved Xiyuan Model

ZHAO Ming-hua,XIAO Yan,CHEN Chang-fu(Geotechnical Engineering Academe, Hunan Univ, Changsha410082,China)  
This paper proposed a complete set of laboratory direct shear experimental process and discussed its details about the rheological property of the soft clay, such as the loading method, the preservation of the test sample, the data acquisition and so on. After studying the present rheological models and the experimental data, we put forward an improved Xiyuan model and its constitutive equation to analyze the experimental results by using the non-linear N element to replace the linear one. The final fitting curves and the value of the parameters indicate that the theoretical results coincide with the experimental ones very well.
