Abstract:
|
Some of the details of EPB tunnelling are difficult to introduce in conventionalnumerical models, nevertheless there are some parameters that can be included in theanalyses in a fairly easy way. The EPB operating pressures are examples of theseparameters. In this paper, the influence of such pressures on the ground movementsand volume losses is examined.The construction of one of Barcelona Line 9 tunnels is taken as the reference casestudy. It is a 9.40 m diameter tunnel excavated in soft deltaic materials, below the ground water level |
