Description du projet
Les infrastructures de transport vieillissantes passent au vert
L’entretien et la modernisation des infrastructures de transport vieillissantes nécessitent des solutions innovantes, durables et à faible émission de carbone pour répondre aux besoins futurs et à l’évolution des charges environnementales induites par le changement climatique. Des opportunités se présentent grâce aux progrès réalisés dans la compréhension et l’exploitation de processus naturels et de pratiques d’ingénierie géotechnique nouveaux et sous-exploités. Pour répondre aux demandes de l’industrie et aux priorités de l’UE en matière de solutions naturelles à faible émission de carbone et de bioéconomie, le projet NOBILIS, financé par l’UE, va explorer de nouveaux processus biologiques in situ. Le chemin de fer britannique servira d’étude de cas pour tester de nouvelles techniques et les évaluer en termes d’impact environnemental et de coûts sur toute la durée de vie.
Objectif
Current EU strategies, the climate action and the European Green Deal require infrastructure to be provided in an economical and environmentally responsible manner, reducing material use, embedded carbon and other impacts on the natural environment and ecosystems. Innovative, low-carbon, sustainable solutions will therefore be needed for the maintenance an upgrading of ageing transport infrastructure facilities to meet future needs and the changing environmental loads due to climate change. Opportunities for transformative processes arise from advances in understanding and harnessing nature-based processes. The use of such processes in geotechnical engineering practice is relatively new and underexplored. Before industrial adoption field applications of the techniques are required to prove their practical viability, long-term sustainability and whole life costs.
The aim of this research is thus to realise exciting new bio-based processes in situ as a viable, sustainable method of improving existing infrastructure earthworks. For this the UK railway network is used as a case study. The research comprises the development of exciting novel processes in the laboratory, their numerical modelling before upscaled application in the field, and a pilot field study application of the novel techniques on a railway embankment. Following this, the techniques will be evaluated in terms of environmental impact and whole life costs. This will lead to practical guidelines for industry, fostering the transfer of new technologies to engineering practice in order to address industry and EU priorities for low-carbon nature-based solutions and bio-economy.
