Structural design model for tunnels in soft soils: From construction stages to …

1. Introduction The increased use of Tunnel Boring Machines (TBMs) in constructing (urban) underground space (Broere, 2016) combined with the fact that most of the world urban population resides in coastal and delta areas, with often soft soil conditions, means that increasingly tunnels are bored in soft layered soils and with decreasing cover.

Ovaling deformations of circular tunnels under seismic loading, …

1. IntroductionThe component that has the most significant influence on the tunnel lining under seismic loading, except for the case of the tunnel being directly sheared by a fault, is the ovaling or racking deformations (Penzien, 2000).Studies suggest that, while ...
