| Summary: | 碩士 === 國立臺灣大學 === 造船及海洋工程學研究所 === 89 === The study of modeling and structural analysis of the dynamic characteristics of the slab track and its dynamics responses under high-speed railway is presented. The slab track is modeled by layered beam with viscoelastic foundation and the natural frequency; mode shape and resonance velocity can be solved with dynamic stiffness matrix of the layered beam structure. With the derivation of the dynamic response under single moving load it can be obtained by applying the same theory that a high-speed railway passed through. Furthermore, the Japanese A-51 slab track will be used as an example to compute the dynamic responses under 3 kinds of high-speed railways: (1) the Japanese S.K.S., (2) the French T.G.V., and (3) the Germany I.C.E.
