Passenger Dedicated Line

Relying on the roadbed in seasonally frozen region of Harbin-Dalian passenger dedicated line，a finite element analysis model was built to study the changing rules of roadbed settlement in construction and operation. The analog and actual results were in good consistence, the model is suitable for the roadbed deformation analysis of high-speed railway in seasonally frozen regions.
