Summary:	隨著橋梁的使用年限增長,其結構安全狀況的監控是確保橋梁安全營運的重要方法,因此,對於位居重要交通孔道之橋梁,依其必要性建構橋梁結構健康監測系統,進行長期監控之工作。本文主要是以高屏溪斜張橋為例,採用監測系統數據進行斜張橋動力監測之研究工作,並以前期實驗資料作為比對之基礎。本文研究的斜張橋主構件包括主梁與鋼纜,由2015年鋼纜和主梁監測資料去探討比對2013年現地試驗結果,在鋼纜部分,首先依據監測值所示別出的鋼纜局部振動頻率,並依據三種不同理論公式計算後求得索力進行比較,其結果顯示,除橋梁左右兩側最長索變化較大外,各鋼纜長期監測值誤差皆在5%範圍內。另外,在主梁部分,各方向主頻的變化不大,惟某些監測資料因儀器異常而監測資料較不完整。總整兩種重要構件之監測結果,斜張橋在過去二年之動力特性變化,尚在可接受範圍內。 Increase with time, the bridge safe is an important issue. The function of bridge health monitoring system is a way to understand structure safe, which can depends on the accuracy of the monitoring data. The effective monitoring information can be adopted to evaluate bridge damage, and the action of bridge closure promptly can react by the early warning indicators. The results will achieve the objective of disaster prevention technology functions by using previous experimental data as a basis of comparison. In this study, the Kao Ping Hsi cable-stayed bridge adopt to determined dynamic characteristics of main beam and cable element , The monitoring data from bridge health monitoring system can be compare to historical data. The results show that varying range of cable is within 5 percent except for the longest and shortest cables. In main beam, it show little change by compare natural frequency except for some monitoring data incomplete because abnormal sensor. In conclusion, the two important components of the Kao Ping Hsi cable-stayed bridge is acceptable about the dynamic characteristics in the past two years.
