Abstract: The large quantity and high filled embankment makes the post-construction settlement very obvious, which influences the operation of the engineering. It is significant to study the method for calculating the post-construction settlement of high filled embankment in order to control the post-construction settlement. The creep deformation is an important component of the post-construction settlement of high filled embankment. Experimental results indicate that the creep deformation of high filled embankment is affected by both time and stress history. A method for calculating creep deformation that can consider stress history is proposed by combining the instantaneous elastic compression line and the framework of the time-dependent unified hardening model. Afterwards, the calculation results are the same as the results of the laboratory creep tests. Besides, the parameters used in the new calculation method are easily to be determined.

Key words: high filled embankment, settlement, creep
