Abstract: An one-dimensional consolidation test under separated loads is conducted to obtain the characteristic creep curves of loess in Yangling Distirct. According to the typical behavior of stress-strain curves of loess under one-dimensional consolidation，an one-dimensional consolidation creep constitutive model is obtained from the relation of parameters and consolidation stress. The relation better simulates the creep characteristics of loess in Yangling District with model test. Besides, based on the experimental results and the secondary consolidation coefficient proposed by Buisman, the relation between the secondary consolidation coefficient and the consolidation stress is obtained. Therefore, a new method of confirming the influence of consolidation stress on the secondary consolidation characteristics is suggested.
