Abstract:In order to study the effect of vertical seismic on the dynamic response
of underground structures, the nonlinear seismic response analysis of a
certain metro tunnel in soft sites was carried out.In the numerical
analysis, a dynamic nonlinear viscoelastic model was used to model the
characteristics of soils under cyclic loading, and the dynamic plastic
damaged model of concrete was selected to model the characteristics of
tunnel lining.The finite element model was established with dynamic
viscoelastic artificial boundary, and the nonlinear seismic response
analysis of the model was carried out with the bottom imposed horizontal
or two-direction seismic wave.The result showed that the vertical
earthquake wave has a great influence on the relative displacement
between tunnel top and tunnel bottom, the stress of tunnel and the
vertical acceleration at tunnel bottom.Therefore, the effect of vertical
earthquake can not be ignored in engineering design
