Abstract

The construction of the western tunnel inevitably encounters the problem of seismic isolation design in high-intensity seismic zones. However, the current anti-seismic calculation methods applicable to tunnel structures mostly adopt the static method and simply increase the stiffness, resulting in overly conservative calculation results and failure to consider the coordinated deformation between tunnel structures. The seismic isolation effect is generally poor. Considering the coordinated deformation between tunnel structures, that is, the coupling effect of stiffness and damping, and taking the generalized composite structure of the tunnel as the object, based on the dynamic equation, integrating the equation relationships of stiffness-damping and other constant parameters, a tunnel seismic isolation layer design method that can achieve precise calculation of stiffness-damping is proposed. Through the calculation of actual engineering cases, this method can solve the optimal values of stiffness-damping of the seismic isolation layer, ensuring that the amplitude of the seismic response of the tunnel structure is minimized under the action of earthquakes. This is of great significance for guiding the selection and design of tunnel seismic isolation layer materials.
