• Description:
  Currently, the knowledge base and quantitative data sets concerning cut and cover tunnel seismic response are scarce. In this report, a large-scale experimental program is conducted to assess: i) stiffness, capacity, and potential seismically-induced nonlinear deformation mechanisms of a representative reinforced concrete tunnel liner, and ii) seismic demand as dictated by the surrounding soil and the tunnel-ground interaction mechanisms. In this regard, the conducted testing efforts allow for more accurate representation of the tunnel reinforced concrete liner configuration, and for use of field soil materials and construction procedures. Based on the recorded experimental data sets, computational studies are performed to further assess the involved soil-structure-interaction mechanisms. Overall, these studies constitute an initial important step towards ultimately providing experimentally validated engineering procedures for use in the development of cut and cover tunnel seismic assessments and design guidelines.
