Damage Monitoring of Ballastless Track Slab Based on Optical Fiber Accelerometer

2021 19th International Conference on Optical Communications and Networks (ICOCN), 2021
A real-time monitoring for ballastless track slab damage based on optical fiber accelerometers is proposed. The field test on the Beijing-Shanghai high-speed railway in China shows that this method can effectively identify the damaged track slabs.

Fatigue Life Prediction of CRTS I Ballastless Slab Track

ICTE 2011, 2011
In order to predict the fatigue life of ballastless track which is at the section of uneven subgrade settlement, this paper uses the CRTS I ballastless slab track as an example. Considering the rebar of slab and base, a detailed vehicle-ballastless slab track-subgrade coupled model was established that was based on ANSYS/ADPL.

Temperature Deformation Analysis of CRTS II Ballastless Slab Track

2013 Joint Rail Conference, 2013
Two finite element models of CRTS II ballastless track superstructure were developed to simulate temperature deformations of the precast concrete track slab. One of the models considered the fully bonding interface between the track slab and the cement asphalt mortar layers, while the other uses cohesive zone elements to simulate possible interfacial ...
