Costa, Pedro Alves; Soares, Paulo; Colaço, Aires; Lopes, Patrícia; Connolly, David

When constructing a new railway line, its long length means there are significant financial implications associated with determining the geodynamic ground properties. Therefore, this paper presents recommendations to optimize the efficiency and depth of such a geotechnical site investigation. Firstly, a numerical analysis is performed to investigate the effect of soil layering, soil stiffness and track bending ...
