碩士 === 國立成功大學 === 土木工程學系 === 89 === The high-speed train is planned to pass though the Tainan Science based Industrial Park, with the total distance around 5 Km. It definitely will cause the vibration of the factories in the Science Park due to the trains. This study is focused on the analysis of how to minimize the vibration impact by various isolated systems. Various isolated systems have been studied, such as isolated planes system﹑ isolated box system﹑open trench system﹑ and combination systems. Finite element technique with plane strain element is used to analysis the possible effect due to a single vertical simple harmonic line load excitation on a well distributed media in a half-infinite domain to investigate the vibration screening effectiveness of various isolated system toward the plane surface of the model. Furthermore, the original vibration source simulated by moving load according to the moving high-speed trains is analysed to investigate the vibration screening effects of the sites with various isolated systems. The vibration screening effect of the sites with the isolated systems will be displayed by some specified sample problems.
