In the 21st century, with the globalization playing an increasingly important and influential role in societies and markets, the development of new transport infrastructures that allow an efficient movement of passengers and goods is of the utmost importance. Railway transport has been playing a key role in this context, contributing to the sustainable development of countries, both in terms of economic growth and social development. This type of transport has several advantages over others, mostly related with the lower transportation costs, the lower environmental impact and safety. Additionally, the reduction in travel time due to the increase of speed, along with an improvement in passenger comfort, also contributes to the greater competitiveness of rail transport.
In order to achieve better performance in terms of travelling time, the railway infrastructure has grown significantly in the last decades, especially with the construction of new bridges and tunnels. In terms of high speed railways, for example, the necessity to ensure smoother tracks with larger curve radius resulted in new railway lines with a high percentage of viaducts and tunnels. Countries such as China and Japan, for example, have high speed networks in which some of the lines have more than 75% of viaducts. Therefore, to face these challenges, the research related to railway infrastructures is becoming increasingly important among the railway engineering community.
Within the framework outlined above, this symposium aims to bring together the latest achievements, research and studies regarding the planning, design, construction, monitoring, maintenance and management of the railway infrastructure.
Theoretical, experimental and computational investigations or a combination of them, are welcome to this session. Expected papers should cover various types of railway infrastructure such as bridges, viaducts, tunnels, track and transition zones. Other relevant topics for discussion will be: vehicle structure interaction, track bridge interaction, soil structure interaction, train-induced ground vibrations, geotechnical aspects (earthworks, embankments and stabilisation), reliability and runnability of railway infrastructure in strong winds and/or earthquake-prone areas.
Railways, bridges and viaducts, tunnels, track, transition zones, earthworks, embankments.
