In order to provide the basement of a further numerical analysis

a series of large-scale triaxial creep tests is performed on gravel-soil obtained from sliding mass of Majiagou landslide in the Three Gorges area. The test results show that the tested gravel-soil is a typical creep material

and its creep deformation characteristics are very obvious. The soil experienced two creep stages

i.e.

the decay creep stage and constant speed creep stage. The data also indicate that confining stress and stress level have an effect on the creep characteristics of soil. Based on these tests

the Singh-Mitchell model is used to predict the creep strain. Compared with the original test data

the Singh-Mitchell model results have good agreement with the experimental data.
