Abstract

Abstract

Based on the creep test data of the slipped zone soils of the Gushubao landslide and experience theory,a new empirical-creep model has been developed. The hyperbolic function is adopted for shear stress-strain behavior and the Morgan Mercer Florin function for strain-time behavior.Parameters of this creep model are presented in this paper by using of the / versus curve and genetic algorithm.Fitting results show that the predicted results are in reasonable agreement with the experimental data. The correlation coefficients of the fitting curves are all above 0.96,which indicates that this creep model can effectively reflect the creep characteristics of the slipped zone soils of Gushubao landslide.
