  • Evaluation of net thrust and torque on mixed-face EPB drives 

    González Paez, Claudia; Arroyo Alvarez de Toledo, Marcos; Gens Solé, Antonio (2015)
    Conference report

    In this communication we propose a way to estimate net thrust and torque applied at the excavation front by cutting tools from EPB machines when they are working in mixed faces constituted by soils and soft rock. The ...
  • Observations of tool wear and excavation performance in urban tunnels 

    González Paez, Claudia; Arroyo Alvarez de Toledo, Marcos; Gens Solé, Antonio (2016)
    Conference report

    One of the most important predictions in a mechanized excavation project is the performance of the excavation Rostami et al., (1994), Bilgin & Balci, (2005). To obtain an efficient ground excavation in mechanized excavation ...
  • Production, performance and maintenance time observations in mixed soil-rock EPB drives 

    González Paez, Claudia; Arroyo Alvarez de Toledo, Marcos; Gens Solé, Antonio (IOS Press, 2015)
    Conference report
