碩士 === 國立屏東科技大學 === 環境工程與科學系所 === 97 === 　Taiwan High Speed Rail has officially been operating more than one and a half year since January 5, 2007. According to the route plan of Taiwan High Speed Rail, it is unavoidable that some buildings are extremely close to viaducts of high speed rail; even the closest distance is less than ten meters. The noise and vibration issues along with High Speed Rail are also very difficult to handle. In this dissertation, Spectrum analyzer has been used to measure the noises and vibrations in and out sides of two buildings where people have been seriously affected, especially in the vibration field, using spectrum analyzer to measure the level of vibrations in the buildings, in order to discuss whether the operation of Taiwan High Speed Rail has produced environment pollutions, and to obey related regulations, discuss whether the vibrations have bad impacts on the residents. 　Using the measurement Leq,1h of 「Environmental Noise Standards」 would not truly reflect the noises and vibrations while Taiwan High Speed Rail moves in high speed. LAmax(mean) should be more representative. According to the measured figures, The noises are comply with the standard of High Speed Rail Lmax recommended value published by Environmental Protection Administration Executive Yuan, R.O.C. but the residents still feel annoyed by the noises and vibrations which Taiwan High Speed Rail has brought with. The main reason is the psychic emotion towards the rapidly increased noises and vibrations, but the current regulations do not request transportations to use low noises and vibrations. Based on the measured figures, The high speed is still the main factor to the noises and vibrations, In the buildings along with high speed rail, the low frequency noises and vibrations have affected the residents’ sleeping. It is not the same in response to examine the vibration acceleration that is clicked in two places, In Renwu Site, The frequency spectrum that examines of benevolence a bit reacts in the largest place and locates in 50 Hz, Secondly it is a range of 12.5 Hz of secondly 5 Hz , and sernei site frequency spectrum most big response that order in 40 Hz, in 3.15 Hz and 10 Hz secondly.
