“…Since then, a series of centrifuge and shaking table tests have been carried to understand the aseismic ability and damage mechanism of underground subway stations. Nishiyama et al [2] proposed a three-level seismic design method for open-trench tunnels based on shaking table tests on subway tunnels and numerical analysis. Iwatate et al [3,4] conducted several shaking table tests on underground subway stations.…”

In this paper, a shaking table test was conducted to investigate the seismic response of the large-span and column-free subway station in the upper-soft and lower-hard strata. The acceleration of the structure and the soil, the dynamic soil pressure, and the strain response of the subway station were obtained and analyzed. The results demonstrate the reasonable test design as the boundary effect was eliminated. The seismic response of the structure and soil became more severe as the acceleration amplitude of the input motion increased. It is indicated that possible shear damage of the soil and irreversible plastic deformation of the structure might have occurred as the test proceeded. The soft clay had a greater effect on the structure than that of the artificial rock. For the model structure, the tensile strain amplitude in the support region was larger than that in the midspan region. The support regions of the roof slab, lateral wall, and middle slab were the vulnerable components of the model structure during earthquakes.

“…The studies relating to seismic response of reinforced concrete in particular provide very promising results with regard to modeling complicated non-linear phenomena, especially material degradation and interfacial slippage (Matsui et al 2004;Nam et al 2006). Nishiyama et al (1999) reinforced the validity of the well established equivalent linear model FLUSH for evaluating deformation response. Despite these successes, the limited number of experimental investigations regarding tunnel structures parallels the limited field observations discussed earlier and sheds light on some important research needs.…”

“…Motivated by the failure of the Daikai subway station, Nishiyama et al (1999) investigated the seismic response of cut-and-cover tunnels through the use of scale model shaking table tests. Model structures were excited with sine waves, and observations were compared with results using various analytical methods.…”

Underground structures perform an important role in transportation systems in many seismically active regions around the world, but empirical data regarding the seismic behavior of these structures is limited. This research works towards filling that empirical gap through the use of scale model shake table testing. Underground seismic soilstructure interaction (USSSI) effects were investigated for a stiff rectangular tunnel crosssection embedded within soft clay. San Francisco Young Bay Mud was used as a prototype soil for developing a scale model soil mixture consisting of kaolinite, bentonite, class C fly ash, and water. A single cell Bay Area Rapid Transit (BART) cut-and-cover subway tunnel was used as the prototype for the 10 th scale model subway cross-section.A flexible walled test container originally developed for a pile study at UC Berkeley was modified for use at Cal Poly, San Luis Obispo. The flexible container allows for close approximation of one-dimensional (1D) free-field site response by significantly limiting the rigidity of the boundary conditions and allowing the soil to deform under simple shear. The study was conducted over two shake
