機場捷運為國內重要交通建設,對於機場捷運土木結構應進行定期或不定期變位監測,並依監測結果分析、研判結構物是否發生位移、傾斜或沉陷,適時提供預防矯正措施,以確保機場捷運結構設施與通車營運安全。
本局委託桃園大眾捷運股份有限公司辦理機場捷運全線結構物監測初始值建置,工作內容包括捷運全線控制測量點及橋梁墩柱、隧道變位初始值及全線導線量測。其中分別於橋梁墩柱及隧道環片設置座標、高程監測點及變位監測點(如附圖),量測機場捷運全線結構變化。
本案桃園大眾捷運股份有限公司業於106年8月4日公告招標,並於106年8月11日決標,預計107年3月8日完成全線建置作業。

The TIAA MRT System is an important national transportation construction so displacement monitoring on its structure should be carried out periodically or unperiodically. According to the analysis of the monitoring results, it is judged whether the structure is displaced, inclined or subsided. Then, the preventive corrective measures are timely provided so as to ensure the safety of the TIAA MRT facilities and the operation of the system.
BOHSR commissioned Taoyuan Metro Corp. to handle the establishment of the monitoring initial value of the entire structure of the TIAA MRT System. The work includes the control points, initial values of bridge piers and tunnel displacements and conducting wire measurement of the entire MRT line. The construction team set coordinates, elevation monitoring points and displacement monitoring points (see attached figure) respectively on the bridge piers and tunnel rings to measure the structural changes across the TIAA MRT System.
The bidding of the Taoyuan Metro Corporation case was announced on Aug. 4, 2017 and was won on Aug. 11. It is estimated that the establishment of the entire route will be completed on Mar. 8, 2018.
