Response and mechanism of a tunnel subjected to combined fault rupture deformation and subsequent seismic excitation
Abstract In this study, sophisticated numerical methods and constitutive models were used to study the effect of combined fault rupture deformation and subsequent seismic excitation on a tunnel. The weakening of the rock-tunnel interface under relative dislocation and degradation of the concrete material in the tunnel liner were considered. The deformation response and failure mechanism of the tunnel subjected to combined fault rupture deformation and subsequent seismic excitation were investigated. The time histories of the relative deformation, the plastic strain, and the tensile strain of the tunnel were studied. The performance of the “joint” design was numerically verified, followed by a detailed parametric study that aimed to provide deep insight into the design factors of the technique of “flexible jointing”. The influences of some important factors were investigated, such as the range of the joints, length of the segments, and length of joint.
