The Wavelength Characteristics of Vertical Deformation and a Train Dynamics Simulation of Long-Span, Cable-Stayed Bridges Under Complex Loads

Applied Sciences
Ballastless tracks have a high smoothness, but the corresponding laying requirements are strict. Therefore, the maximum span of cable-stayed bridges that can accommodate ballastless tracks is 392 m.

Changes in Material Properties and Damage Mechanism of Plate Ballastless Track Under Fire and High Temperature

Buildings
The service status of rail, fasteners and track slabs is the key determinant of whether the ballastless track is ready for traffic after a fire. The track slab rail support bolt anchoring performance and the shoulder service performance damaged by fire ...

Structural state detection using quaternion-based three-channel joint transmissibility [PDF]

, 2015
This paper presented the use of quaternion-based three-channel joint transmissibility (QTJT) in structural state detection. During the detection process, the time-domain pure quaternion sequences were obtained based on the three dimensional spatial ...

The financial and economic assessment of China's high speed rail investments: A preliminary analysis [PDF]

, 2013
China has suffered railway capacity constraints for more than several decades and the need for a large increase in rail capacity has been viewed as the primary challenge. The former Chinese Ministry of Railways believed that building a national wide high
