• Abstract:
  With the increasing demand for tunnels in sensitive urban environments, pressure balance mechanized tunneling is employed in most soft ground tunnel construction projects. Segmental tunnel lining is used in pressure balance mechanized tunneling as temporary and final support. With common service life requirements of 100 and even 150 years, efficient design of pre-cast concrete segments can have considerable serviceability and economic importance. The aim of this thesis is to improve the understanding of ground-structure interaction of segmental lining in soft ground mechanized tunneling both in the main running tunnels and at cross-passage openings. Incorporating rare field data collected from the Northgate Link project in Seattle together with advanced three-dimensional (3D) finite-difference modeling (FDM), this research seeks to provide insight into segmental lining ground-structure interaction.
