Study on triaxial compression creep test and numerical simulation about mud rock in southern Shaanxi

Based on the indoor triaxial compression creep test of the mud rock in southern Shaanxi,the parameter values of Burgers model about the mud rock are determined,and the rheology characteristics of the mud rock are described.The results showed obvious three stages of the creep curves of the mud rock with the increase of load,and the total creeping values of the sample is quite large.The simulation about the triaxial compression test under the confining pressure of 1MPa is numerated by the FLAC3D s...
