Dynamic behaviors of subway structure subjected to strong earthquake motions using shaking table tests and dynamic analyses
In order to clarify the dynamic behaviors and the damage mechanism of the subway structure
a series of shaking table tests and dynamic finite element analyses of Dakai subway station damaged in 1995 Hyogoken-nanbu earthquake were performed.The mechanism of the seismic soil pressure acting on the structure
the effects of the input directions of the sinusoidal and random waves
the embedded depth of the subway structure and the shear modulus ratio between the structure and the surrounding ground were investigated.Moreover
from the nonlinear seismic response analysis
the seismic soil pressure in the limit state of the surrounding ground were evaluated.It was resulted that the seismic soil pressure would reach a peak value;and the seismic soil pressure consists of dynamic component and static one caused by residual strain of the ground due to strong earthquake motions.The foundation is provided for amending the calculation method of seismic soil pressure and improving the anti-earthquake designing level of underground structure.
