Abstract: 

Two dimensional harmonic response of lined circular tunnel in elastic full space medium against plane P-SV waves is investigated .The solution uses hybrid direct boundary element method and finite element method for soil and lining, respectively. In the proposed ring element used in the modeling of lining, radial and tangential deformations are defined using Fourier series expansion. Therefore the direct unknowns of problem are introduced as coefficients of these series. Numerical results include the non-dimensional shear and hoop stresses in lining as well as its interface with surrounding soil for various material properties.
