About this Research Topic
A track transition is defined as a section of track where the track stiffness undergoes a drastic change. Common examples of track transitions include: bridge approaches, tunnels, grade crossings, and transitions between sections of ballasted and ballast-less track (or slab track). The transition zone is often a crucial part of the railroad track structure which undergoes large differential settlement, as a result of the additional dynamic loads owing to sudden change in the stiffness of track superstructure and the foundation. In order to reduce the costs of maintaining these zones, the fundamental mechanisms of loading, stiffness and settlements need to be fully understood.
This issue is designed to accommodate the interests of industry professionals and academic researchers in monitoring, modeling, and designing of track transitions . Developing appropriate models and methods for dealing with track design and substructure material issues can be challenging to railroad practitioners. To address some of these challenges, the topic involves a wide coverage of timely issues on modern railroad technologies focusing on broad aspects of geotechnical and structural innovations in order to faciliate sustainable performance of track transitions .
Potential topics include but are not limited to the following:
- Track loading and stability
- Track degradation and maintenance
- Track and Ground Improvement Methods
- Field Monitoring and Sensing Technologies
- Analytical and Numerical Modeling
- Remedial Measures to Address Differential Movement at Track Transitions
- Applications and Case Studies in Geotechnical Engineering
Keywords: Railway, Deformation, Degradation, Modeling
