Full-scale experimental and field investigations into expansion mechanism of foamed polyurethane and its lifting behaviors for repair and maintenance of railway slab track systems [PDF]

Excessive settlement of the subgrade seriously reduces the service quality of slab tracks and threatens trains’ running safety. While the utilization of foamed polyurethane is recognized as an effective solution, previous research on its expansion ...

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.

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 ...

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 ...
