With the improvement of semiconductor processing, wafer factories are becoming more sensitive to micro- vibrations because of the precision requirement during production. But two national scale projects of Taiwan: Taiwan High Speed Railway (THSR) and Tainan Science Park (TSP) are compelled to be adjacent. So the “high speed rail vibration problem” receives the attention from the circles. The purpose of this article is to develop a long-term continuous monitoring system to observe the Hybrid Vibration Mitigation System (HVMS) which is used to prevent the ground vibration caused by passing trains from impacting the vibration-sensitive factories in the science park. The monitoring system contains two major parts: (1) Ground vibration measurements in TSP: To monitor the ground vibration induced by traveling train with taking same vibration measurements both inside and outside of TSP (where no ground vibration mitigation devices are installed) at the discrete points lying on the straight line perpendicular to the THSR alignment at the distance 0m, 100m, 200m, 400m and 600m from the THSR-alignment centerline and contrast the effectiveness of the constructed HVMS. (2) Screw bolts mechanics measurement of Frictional Connection Block (FCB) : FCB is a part of HVMS’s design, which is used to connect the other part of HVMS, Foundation Stiffening Block (FSB) with the viaduct pile caps by frictional force.The frictional force is in relation with the axial force induced by screw bolts. Mechanic characteristics measurement is taken to confirm the capability of HVMS.摘要 ABSTRACT 目錄 IV 1.1 研究動機與目的 1 1.2 文獻回顧 3 1.3 本文內容 5 第2章 台南科學園區減振工程之振動監測 6 2.1高速列車行經高架橋衝擊大地之震波傳遞現象 6 2.2 複合減振系統 7 2.2.1 台南科學園區減振工程之設置 7 2.2.2 HVMS 設計概念 9 2.2.3 HVMS結構數值模擬分析 11 2.3倍頻頻譜 14 2.3環境振動頻譜的分析 14 2.4列車振動影響時段 17 第3章 量測系統 20 3.1振動監測 20 3.1.1 監測位置 20 3.1.2 硬體規格 21 3.1.3 量測方法： 23 3.2固鎖監測 27 3.2.1監測位置 27 3.2.2 硬體規格 32 3.3 量測程式 35 第4章 量測結果討論 38 4.1 振動量測結果 38 4.1.1量測資料編號說明 38 4.1.2 列車通過引起大地振動量測結果討論 55 4.2 螺栓固鎖量測結果 59 4.2.1量測資料編號說明 59 4.2.2量測結果 62 4.2.3螺栓固鎖量測結果討論 93 第5章 結論與未來展望 96 5.1 本文總結 96 5.2 未來展望 98 參考文獻 992375799 bytesapplication/pdfen-US高速鐵路環境振動1/3倍頻頻譜減振工程量測系統high speed railwayvibrationone-third octave spectrumvibration mitigation systemmeasurement[SDGs]SDG8thesishttp://ntur.lib.ntu.edu.tw/bitstream/246246/51081/1/ntu-96-R94525008-1.pdf
