- Abstract:
- Assuming that the lining and the soil skeleton are a viscoelastic medium with Kelvin - Voigt modelthe problem of steady state responses of a cylindrical lining struclure with parial sealing subjected to asymmetric radial loading and fuid pressure is investigated using an analytical method in the frequency domain. TheBiot’’s theory and viscoelastic theory are used to describe the saturated soil and lining struclure, respectively.The analytical solutions for the dynamic interaction af saturated viscoleastic soil and lining structure are ob.tained with help of potential functions under partial permeable conditions of the tunnel’s boundary, By utili-.zing, the inner boundary condition of the lining structure and the continuity conditions between the soil and thelining, the unknown coefficients in the expressions of displacement, stress and pore water pressure are deter.mined. On this basis, the influences of the coefhcients of permeable and fluid compressibility, viscous damp.ing coefficient of lining on dynamic responses of the soil and lining are analyzed. A comparative analysis be.tween the results of this paper and existing ones is carried out.
