- Abstract
Summary: A semianalytical procedure is proposed for evaluating the internal forces of circular tunnel with imperfect interface bonding in layered ground subjected to an obliquely incident plane P or SV wave. In this study, the hoop bending moment and hoop axial force are related to the free‐field responses of the ground. A one‐dimensional numerical approach is firstly presented to obtain the free‐field responses of a layered half‐space with an obliquely incident plane P or SV wave propagation. Then, the free‐field stress state is transformed and decomposed in the polar coordinate system. The internal forces of tunnel caused by the isotropic stress state and the pure shear state are calculated and then summed up to obtain the overall analytical solutions. Finally, the validity of the proposed semianalytical procedure is demonstrated by numerical examples.
