Abstract: In the traditional teaching system, “Tunnel Engineering" focuses on the single tunnel structure as the core research object. However, in the current engineering context of the development of rail transit networks, this teaching system reveals certain theoretical limitations. Currently, double parallel tunnel structures are widely emerging in engineering practice. The dynamic response mechanism of such structures has exceeded the analysis scope of traditional single tunnel theory. This paper combines the theory of “Structural Vibration" to construct a dynamic analysis model for double parallel tunnels. Combined with the Euler-Bernoulli beam theory, an analytical solution for the vibration response of double parallel tunnels under axial compression is derived. The analytical method constructed in this paper can provide students with a complete mechanical modeling demonstration, strengthening their understanding of the basic methods and ideas for solving structural vibration problems in tunnel engineering. This effectively compensates for the theoretical deficiencies of traditional textbooks in the dynamic analysis of tunnel structures and provides theoretical support for constructing a teaching system for structural vibration analysis oriented towards modern underground engineering.
