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.

Reliable Basis

The development of high-speed railway construction and operation greatly shorten people's travel time, however, the demand of people on travel time reliability becomes more and more prominent, so train dispatching plans are becoming more and more important. This paper defines probabilistic conflicts between trains, analyses probabilistic conflict influence factors and comes up with a method for predicting probabilistic resource conflicts between trains. The method aims to improve the accuracy of train conflict prediction, provide more reliable basis to solve train conflicts and develop more efficient train dispatching plans.
