《隧道工程》到《结构振动》−分析双平行地铁隧道振动响应窥见课程应用

FROM "TUNNEL ENGINEERING" TO "STRUCTURAL VIBRATION" − ANALYZING THE VIBRATION RESPONSE OF TWO PARALLEL SUBWAY TUNNELS TO GAIN INSIGHT INTO COURSE APPLICATION

  • 摘要: 在传统教学体系中,《隧道工程》以单一隧道结构为核心研究对象。但在当前轨道交通网络化发展的工程背景下,这一教学体系显露出一定的理论局限性。当前工程实践中广泛涌现出双平行隧道结构。这类结构的动力响应机理,已超出传统单隧道理论的分析范畴。本文结合《结构振动》课程理论,构建了双平行隧道动力学分析模型。并结合Euler-Bernoulli梁理论,推导了轴压下双平行隧道振动响应解析解。本文所构建的解析分析方法可为学生提供完整的力学建模示范,强化其对隧道工程结构振动求解基本方法和思路的理解。这有效弥补了传统教材在隧道结构动力分析方面的理论不足,为构建面向现代地下工程的结构振动分析教学体系提供了理论支撑。

     

    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.
