Chengdu - Mianyang – Leshan (C-M-L for short) high speed railway in Chengdu section is located in the ground of weathered Mud rock overlying deep Chengdu clay area. Based on Chengdu clay ground of in high-speed railway construction project of CML, this article introduced the Burgers model to establish the objective function to analysis rheological constitutive model. The visco-elastic parameters of Burgers model are determined by back analysis of field monitoring data. By the method of iterative back analysis by layer of visco-elastic parameters, based on measured result, predicted the late settlement, and comparison with the follow-up observations records to verify the Burgers model.

Settlement prediction is an important method to judge whether the post-construction settlement of the high-speed railway foundation satisfies the requirement of the standard. The paper uses the numerical calculating method based on creep model to predict the subgrade post-construction settlement of the surcharge preloading processing segment of the high-speed railway through inversing the creep parameters, and does comparative analysis with the more researched function fitting methods. The conclusion is that: (1) the numerical calculating method based on creep model is feasible to predict the post-construction settlement; (2) the method can predict the settlement trend with any time starting point; (3) the method can predict the settlement with relatively less actually measured data so as to saving project cycle.
