Abstract

Shallow underground structures used for public transportation are a key component of sustainable cities. In dense urban environments, underground structures are often built near tall buildings. Although such buildings have the potential to alter ground motions in their vicinity and transmit forces to adjacent underground structures during earthquakes, these impacts are not well understood. Centrifuge testing and nonlinear numerical simulations are being performed to evaluate seismic interactions between soil, underground structure, and an adjacent mid-to high-rise building. This paper presents the experimental setup, instrumentation performance, and brief results from the first baseline centrifuge test on a permanent cut-and-cover box structure with no buildings present. Preliminary results presented include box racking deformations and estimated dynamic lateral earth pressures.
