Simulation on the Creep Deformation of Reticulate Red Clay

Abstract

One-dimensional consolidation tests were performed on the undisturbed and remodeled specimens under different consolidating pressure. By analyzing the laboratory test results, following conclusions were drawn: (1)the creep deformation of undisturbed specimen is much smaller than that of remodeled one; (2)although there is steady creep stage of undisturbed reticulate red clay, creep curves of undisturbed specimen in this stage are rough, while the creep curves of remodeled specimen in the same stage are smooth; (3) the difference between the times to obtain stable displacement of remodeled and undisturbed specimen decreased as the consolidating load increasing, while the difference between the stable displacements increased significantly. It was also found that the one-dimensional consolidating curves of reticulate red clay can be simulated with linear equation very well.
