| Popis: | 102 Fourteen automatic environmental vibration monitoring stations were established by the administration office of Southern Tainan Science Park (STSP) in 2002 to measure the environmental vibration in the Tainan Science Park. The ground vibration velocity data were collected from 2002 to 2013, and reduced using one-third octave spectrum. The results were presented by daily maximum amplitudes, daily average amplitude, the difference of amplitude of day and night, and significant response frequency of free-field. According to the long-term analysis results, the vibration data can be approximately divided into three phases. The change of vibration amplitude in each station is large while the construction phase of high-speed rail and high-tech factories (2002-2007). The amplitude difference between day and night is about 2~12dB. The difference between the amplitude values in day and night went down to 2~6dB while the manufacturers and personnel moved in (2007-2011). The amplitude changes are approximately 2dB in the stable phase (2011-2013). |
