Abstract
A series of creep tests on high salt saturated fine sand under different stress and salt content were carried out by uniaxial compression test. Based on the classical K-H body model of three elements and the Bu body model of four elements on the linear viscoelastic plasticity theory, a creep model of five elements under the consideration of the comprehensive effect of salt water soil is proposed combined with the experimental analysis results under different stresses and salt content. The analysis results show that the creep model of the five element can fit well the creep law of high salinity fine sand under different stress and salt content, and the validity of the model is proved by comparing the three models and comparing the experimental data with the fitting results.
