| Abstract |
In this paper, we derive the analytical solution for the dynamic stress concentration factor (DSCF) of a lined tunnel buried in a homogeneous half space where plane SH waves are incident, by applying the complex function method. The conformal transformation is used to obtain an accurate solution for the corresponding boundary value problem. A physical plane with a cylindrical line is mapped into an image plane consisting of three concentric circles by expressing the wave potentials of the medium in terms of a complex variable and introducing the conformal mapping. By applying the boundary conditions on three surfaces and the principle of orthogonality of trigonometric functions, a system of an infinite number of equations is constructed and the unknown coefficients for the scattered wave functions are calculated. In order to confirm the accuracy of the method, the solution results are compared with the results obtained in the previous studies. Then, the DSCFs on the outer and inner surfaces of the tunnel wall are calculated considering the several parameters of media and various conditions, and the results are discussed. |
