碩士 === 國立臺灣海洋大學 === 系統工程暨造船學系 === 93 === Abstract
The purpose of this thesis is mainly to establish the prediction model of ground borne vibration induced by surface and underground track systems. Basically, the analysis model on soil vibration is based on the finite element method (FEM). To validate the correctness of the prediction model, two experiments are carried out for comparisons. One experiment was a dropped weight experiment undertaken on the area of Ding-Pu Science Park of the extension route of Tu-Chern line of Taipei (MRT). The measured ground borne vibration data are compared with that obtained by FEM, in which only the soil is modeled. While the other experiment is carried out at Chiang Kai-Shek Memorial Hall station of Xindian line of Taipei MRT. Also the measured ground borne vibration spectrum is compared with that attained by FEM, in which both the soil and the tunnel wall structure are taking into consideration. The input excitation is determined by measuring the train passing by and vibration impact test at the same site. Both comparisons show that the error is within 2~11persent, which validates the prediction model.
An application example is the modeling of the Xin-Yi line of Taipei MRT, the prediction of ground borne vibration has discussed. Also, the regression curve of ground borne vibration at different distance generated by passing train is obtained. This result can also be used to predict the ground borne vibration of passing train through cross-overs, curved sections, and the rail before and after grinding.
