The boundary integral equation method involving the Green's function by the thin layer method is very useful for the analysis of the excavated multi-layered visco-elastic soil. However, there exist two complexities in this method ; 1) the calculation of the stress components of the Green's functions introduces substantial errors near the applied point, 2) the solution of the dynamic stiffness analysis is disturbed in wide range near the natural frequency of the internal region. This paper resolves both of these complexities at once by putting several constraint panels in the internal region. Those panels are used for the purpose of taking away the internal resonance point from the frequency range of interest and deriving the conditions to modify the solution of the stress. In order to show the validity of the present method, this paper presents the dynamic torsional stiffness analysis of the axi-symmetric excavation.
