Influence of Uneven Subgrade Frost Heave on Deformation and Damage of CRTSIII Slab Track
The problem of uneven frost heave deformation of high-speed railway subgrade in seasonal freezing areas seriously affects the service state and service life of slab track structures and threatens the safe operation of high-speed vehicles.Based on the damage plasticity theory of concrete, in this study, an analytical model is established for CRTSIII
