Bridges represent a significant proportion of high-speed railway (HSR) lines in China, and
high-speed trains operate on these structures for prolonged periods. Consequently, the …

Due to the wide railway network and different characteristics of many earthquake zones in
China, considering the running safety performance of trains (RSPT) in the design of high …

Temperature is an important load for ballastless track. However, there is little research on
the system dynamic responses when a train travels on a ballastless track under the …

In response to long-term operation of prestressed concrete railway bridges, the girder body
will arch because of creep, which may influence the running stability of high-speed trains …

Wheel flange climb derailment of vehicles in railway turnouts is a serious safety issue. In
particular, derailment accidents in smaller turnouts, caused by poor track alignment before …

Rail irregularity presents a major threat to the high-speed train (HST) safety on a high-speed
rail (HSR) bridge. Lateral bridge deformation has a significant impact on geometric …

The development of reliability theory has led to the setting of tasks requiring consideration of
the efficiency and functional safety of technical objects of transport over the life cycle. The …

China has the largest network of high-speed railway (HSR) lines in the world. Since most of
China's territories are within seismic zones, many HSR lines are under the threat of …

Train–track–substructure dynamic interaction is an extension of the vehicle–track coupled
dynamics. It contributes to evaluate dynamic interaction and performance between train …

An improved spatial vehicle–track–bridge interaction system considering the unsupported
track is proposed using the virtual work principle. When the track fails to be supported due to …
