Geotechnical design of railway embankments – requirements and challenges

Detecting Plants on Railway Embankments

This paper investigates problems concerning vegetation along railways and proposes automatic means of detecting ground vegetation. Digital images of railway embankments have been acquired and used for the purpose. The current work mainly proposes two algorithms to be able to achieve automation. Initially a vegetation detection algorithm has been investigated for the purpose of detecting vegetat...

Design requirements: Challenges and approaches

The visions are changing as well; for example, attractiveness and excitement factors bring user experience design and marketing to the forefront of competitive advantage that have rarely been considered in RE research. In the financial crisis, we have once again learned how important costs are but we still poorly understand the costing and the financial impacts of complex projects. Systems that...

Static and Dynamic Analyses of Micropiles to Reinforce the High Railway Embankments on Loose Beds

Construction of railway embankments on loose beds without using any methods of soil improvement (e.g. stone columns in silt and clay beds, deep soil mixing method, jet grouting and also using micropiles individually or in groups form) leads to  reduction of embankment slope gradient, which significantly increases the volume of soil operation. Generally, micropile as a reinforcing element with t...

A Numerical Study on Geofoam Application in the Settlement Reduction of Railway Embankments

Construction of railway track embankment over a soft subgrade will bring the necessity of using soil improvement methods for bearing capacity and settlement criteria satisfaction. As a practical improvement method, railway embankment filled with geofoam blocks is studied in this paper. First; a bilinear stress-strain model developed in FLAC2D to simulate geofoam embankment behavioral model. Sec...
