| Popis: | 94 In order to balance the development of Hi-Tech industry between the northern and southern regions, the government began to establish the Southern Taiwan Science Park at Hsin-Hua in 1997. It has already become an important city for developing Hi-Tech industry in the Southern Taiwan. The high speed train will pass through the park, this will cause the serious vibration problem for the Hi-Tech Park. This research is to study and analyze the relevant vibration, such as vibration induced by high speed train, at the ground surface. This research mainly sets up a standard method and operational procedure for measuring the ground vibration induced by the high speed train. It attempts to find the trend influenced by the vibration in the different train speeds. It can reduce the impact to local area effectively without paying any extra terms, and offer the reference for relevant organizations to research and make policy. The software used in this study is developed by ourselves in the laboratory for data acquisition and measurement analysis. We found that the result was matched with that of other organizations. This research shows that the trend of vibration amplitude spectrum is approximately equal for the train going to the south or the north if the train's speed is the same. The distribution of the main train's vibration frequency is proportion to the train's speed, but the real trend of spectrum distribution of every train is different from the measuring results. In conclusion, we suggest that when the train passes through the site, the train speed should not be in the range from 260km/hr to 300km/hr except for the policy need. And, also the speed should avoid being 160km/hr. The optimum speed is the range from 230km/hr to 240km/hr. If the train speed is limited to less than or equal to 120km/hr, the influence of vibration induced by train will be reduced the most. |
