Track–bridge interaction (TBI) is an increasingly essential consideration for the design and operation of railway bridges, especially innovative bridge structure systems that constantly spring up over years. This paper focuses on characteristics additional forces in continuous welded rails (CWRs) 3 × 70 m integral rigid-frame Fuzhou–Xiamen High-Speed Railway, which a novel high-speed (HSR) syst...

Original scientific paper The objectives of this paper are to perform a comparative analysis of the large-scale system of a high-pier railway bridge subjected to stationary and nonstationary spatially varying earthquake excitations using the pseudo-excitation method (PEM), and to estimate whether or not the non-stationary stochastic analysis of the high-pier railway bridges under tri-directiona...

At present, reducing subgrade settlement of soft soil foundation is a key problem in high-speed railway construction. Pile-slab structure is a widely-utilized form of foundation structure to reduce the subgrade settlement in China. In order to save the engineering cost for high-speed railway construction in developing countries, the author developed a pile-slab structure and named it as the new...

Railway capacity is not only the basic condition for the allocation of railway resources but also an index set for the evaluation of the usage of them. Sometimes the maximum theoretical results calculated according to the coefficient methodology for the capacity calculation of the Existed Chinese traditional railway (abbreviated as ECTR) would be less than those statistical results from the rea...

Railway track components located at bridge transition zones or approach areas suffer from impact load and vibrations caused by abrupt changes in track stiffness on the bridge and the subgrade. The numerous strategies that can be used to mitigate these abrupt track stiffness changes rely on one of two concepts. The first concept is that of providing a gradual stiffness change, and the second is ...

Bridge expansion joints (BEJs) are equipped at the girder end of long-span railway bridges to ensure reliable transition track. BEJs should have suitable dynamic stiffness running safety and stability vehicle. To explore influence vertical on response vehicle, track, bridge, a three-dimensional vehicle-track-bridge coupled model is established, sleeper spacing vehicle speed taken into considera...
