Vibration characteristics of metro tunnel structures based on theory of moderately thick cylindrisscal shells
摘要
Abstract
Taking metro tunnels in soil as research background, at first, according to the theory of moderately thick cylindrical shells considering transverse shear deformation, a vibration equation for tunnel structures is established.Secondly, a motion equation for the soil around the tunnel is set up by use of the Navier's wave theory of homogeneous, isotropic, linear elastic media.Based on these, taking advantages of the wave propagation approach, a vibration control equation for tunnel structures considering soil-structure dynamic interaction is established through the continuous conditions of interface, and then, by making use of its dispersion characteristic equation, the vibration characteristics of the tunnel structures are analyzed, which validates the effectiveness of the equation gained above by comparing with the corresponding results obtained by using the thin shell theory and the finite element method.Furthermore, the influences of radius, wall-thickness, length and buried-depth of the tunnel on the vibration characteristics of the structure are also analyzed.关键词
