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 ... -
Numerical Simulation of Bitumen Emulsion-Stabilised Base Course Mixtures With C&D Waste Aggregates Considering Nonlinear Elastic Behaviour
Pérez Pérez, Ignacio; Medina-Rodríguez, Luis; Gómez Meijide, Breixo; Alves Costa, Pedro; Cardoso, A. (Elsevier, 2020)[Abstract:] This study presents the numerical modelling of a load-volume road pavement section with bitumen emulsion-stabilised base courses. The base courses used natural and construction and demolition aggregates. A 3D ... -
Predicting Critical Speed of Railway Tracks Using Artificial Intelligence Algorithms
Ramos, Ana; Castanheira Pinto, Alexandre; Colaço, Aires; Fernández Ruiz, Jesús; Alves Costa, Pedro (MDPI, 2023)[Abstract:] Motivated by concerns regarding safety and maintenance, the operational speed of a railway line must remain significantly below the critical speed associated with the track–ground system. Given the large number ... -
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 ...
