Structural performance of ballastless track slabs reinforced with BFRP and SFCB
Composites Part B: Engineering, 2015Abstract Because of the inductive impedance caused by steel meshes in traditional reinforced ballastless track slabs, the electrical properties, primarily the rail resistance and inductance, of jointless track circuits are affected by electromagnetic induction between the slabs and the electric current in the rail.

Fatigue Performance of Ballastless Track Slabs Reinforced with BFRP and SFCB
Journal of Composites for Construction, 2017AbstractThe main objective of this research was to evaluate the behavior of fiber-reinforced polymer (FRP) bar-reinforced ballastless track slab subjected to a fatigue loading. Five ballastless track slabs were experimentally tested, which were reinforced with steel fiber–reinforced polymer composite bars (SFCBs), basalt fiber–reinforced polymer (BFRP)

Fatigue Life Prediction of CRTS I Ballastless Slab Track
ICTE 2011, 2011In 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, 2013Two 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 ...

Temperature has a significant impact on the structural performance of the China Railway Track System (CRTS) Ⅱ slab ballastless track-bridge and the structure is susceptible to fatigue damage under long-term loading. Therefore, it is crucial to conduct cyclic-loading test on the track-bridge structure to reveal the evolution of its mechanical properties

Mud Pumping in Ballastless Slab Track of High-Speed Railway and Its Remediation
2021Mud pumping is an increasing subgrade distress in ballastless slab track of high-speed railway, which heavily affects the driving comfort and even threatens the driving safety. However, the existing researches mostly focused on the water-induced distress in ballasted railway, and little attention was paid on the mud pumping in ballastless slab track ...
