Comparison and Verification Analysis on the Fitting Curves of Several Different Creep Models

Abstract:

Soft rock has a strong rheology behavior and displays different creep process under the different stresses. According the experimental data from the sandstone creep test, firstly the paper fitted and compared several different creep models, got the optimized sandstone creep model under the condition of low stresses, finally the paper determined its model parameters under the condition of different pH and differential stresses with the program of MATLAB who have certain reference value.
