The mechanical performance of China Railway Track System type II (CRTS II) ballastless track suitable for High-Speed (HSR) bridges is investigated in this project by testing a one-quarter-scaled three-span specimen under thermal loading. Stress analysis was performed both experimentally and numerically, via finite-element modeling the latter case. results showed that strains slab, cement-emulsified asphalt (CA) mortar bed, increased nonlinearly with temperature increase. In longitudinal...
To study the mechanical properties of China Railway Track System type II (CRTS-II) ballastless slab track structure, a 1/4-scale specimen CRTS-II track-32-m standard prefabricated simply supported box girder bridge with three spans and two high-speed railway lines was developed. The structure under action daily natural temperatures were studied environmental conditions. structural strain relative interlayer displacements analyzed. results show that temperature track-bridge system changes...
To study the evolution of mechanical properties steel rebars in China Railway Track System Type II (CRTS II) ballastless track–bridge structural system under repeated train loads, a 1/4 scale three-span slab track simple-supported bridge specimen was manufactured and subjected to multistage fatigue test with 18 million cycles. The experimental results show that strain amplitude bar changes proportionally stress amplitude, there is an obvious increase loading stage 4, where largest. During...
