Abstract: To investigate the stability of loess slope in Fufeng district of Shaanxi province, we carried out drained triaxial creep tests of unsaturated remoulded loess by SR60, a traixial creep instrument. Test results show that the creep characteristics of loess is obviously influenced by water content, confining pressure and consolidation pressure. The creep strain grows much bigger, and the creep phenomenon is quite obvious when the water content is higher and confining pressure is lower. Meanwhile, with other condition invariable, the creep strain increases with the growing of consolidation pressure. On the basis of analyzing test data, we proposed an empirical creep model and compared it with Singh-Mitchell model and Mesri model. The comparison reveals that the model is of high accuracy and easy-obtained parameters in simulating the creep characteristics of loess.
Key words: unsaturated remoulded loess, triaxial creep, empirical creep model, models comparison , water content, consolidation confining pressure, deviatoric stress
