Critical Length of Encased Stone Columns
Miranda, Marina; Fernández Ruiz, Jesús; Castro González, Jorge (Elsevier, 2021)[Abstract] Encased stone columns are vertical inclusions in soft soils formed by gravel wrapped usually with a geotextile. Their critical length is the one where further lengthening of the column provides a negligible ... -
Estudio numérico de vibraciones provocadas por el tráfico ferroviario en túneles en el dominio del tiempo: análisis geotécnico, validación experimental y propuesta de soluciones
Fernández Ruiz, Jesús (2014)[Resumen] Esta tesis doctoral desarrolla un modelo numérico tridimensional y bidimensional para el estudio de vibraciones provocadas por el paso ferroviario en túneles con sistemas de vía en placa mediante modelos de ... -
Improvement of the Critical Speed in High-Speed Ballasted Railway Tracks With Stone Columns: A Numerical Study on Critical Length
Fernández Ruiz, Jesús; Miranda, Marina; Castro González, Jorge; Medina-Rodríguez, Luis (Elsevier, 2021)[Abstract] The pressure to achieve a higher speed of train operation has increased in the last few years due to the development of high-speed railway lines. In the presence of soft soils, this speed increase is not possible ... -
Influence of non-linear soil properties on railway critical speed
Fernández Ruiz, Jesús; Castanheira Pinto, Alexandre; Alves Costa, Pedro; Connolly, David Patrick (Elsevier, 2022)[Abstract:] The design of high-speed railway lines involves geotechnical challenges, one of which is the risk of dynamic track amplification, for example on track sections where the train speed approaches the track-ground ... -
Long-term non-isothermal reactive transport model of compacted bentonite, concrete and corrosion products in a HLW repository in clay
Mon, Alba; Samper, Javier; Montenegro, Luis; Naves, Acacia; Fernández Ruiz, Jesús (Elsevier, 2017)[Abstract:] Radioactive waste disposal in deep geological repositories envisages engineered barriers such as carbon-steel canisters, compacted bentonite and concrete liners. The stability and performance of the bentonite ... -
Numerical Simulation of the Stiffness Evolution With Curing of Pavement Sections Rehabilitated Using Cold In-Place Recycling Technology
Orosa, Pablo; Medina-Rodríguez, Luis; Fernández Ruiz, Jesús; Pérez Pérez, Ignacio; Pasandín, A.R. (Elsevier, 2022)[Abstract] Cold in-place recycling (CIR) technologies are becoming one of the main bets in the road sector to promote the reduction of greenhouse gas emissions. This technique also contributes to the circular economy, ... -
Use of Tyre-Derived Aggregate as Backfill Material for Wave Barriers to Mitigate Railway-Induced Ground Vibrations
Fernández Ruiz, Jesús; Medina-Rodríguez, Luis; Alves Costa, Pedro (MDPI, 2020)[Abstract] The use of piles as barriers to mitigate vibrations from rail traffic has been increasing in theoretical and practical engineering during the last years. Tyre-derived aggregate (TDA) is a recycled material with ...
