Numerical simulation of seismic response of an underground structure in liquefiable soils
This study presents a numerical simulation of the seismic behaviour of a water intake and outlet tunnel, which is built at a power plant in shanghai. Analysis of the seismic response of this underground structure in liquefiable soils is carried out by means of the finite element method based on Biots consolidation theory. The behaviour of the tunnel ground soils is described by a cyclic elastoplastic constitutive model which was developed within the framework of the Armstrong-Frederick type non-linear kinematic hardening concept. Such aspects of seismic responses as displacements, accelerations, and excess pore water pressures of the tunnel in liquefiable foundation soils are assessed and discussed in this paper. The numerical results prove that the application of the numerical model can obtain basic liquefaction characteristic of this under- ground structure in liquefiable soils. Some scientific suggestions on earthquake resistant design of similar engineering projects can refer to the results of this study.
