dc.description.abstract	Some of the details of EPB tunnelling are difficult to introduce in conventional numerical models, nevertheless there are some parameters that can be included in the analyses in a fairly easy way. The EPB operating pressures are examples of these parameters. In this paper, the influence of such pressures on the ground movements and volume losses is examined. The construction of one of Barcelona Line 9 tunnels is taken as the reference case study. It is a 9.40 m diameter tunnel excavated in soft deltaic materials, below the ground water level
