摘要

隧道因為受到外力作用、材質劣化或者是其他因素而產生異狀時，最直接的反應便是在混凝土襯砌上形成裂縫及滲水的現象。目前常用之檢測方法仍沿用一般混凝土結構物之調查技術，例如目視法、透地雷達掃描及鑽心取樣等。但是隧道為長條形之地下封閉結構物，與一般地上開放結構物不同，傳統之調查技術往往無法滿足其效率及精度上之要求。有鑑於此，擁有悠久隧道歷史的歐洲率先針對隧道襯砌裂縫、滲水、襯砌背後空洞及淨空大小發展了一套結合影像、熱像及淨空掃描的自動化檢測系統，利用載具配合360度旋轉的掃描感應器，可以快速、精準地一次取得隧道全線影像、溫度及淨空資料，以作為隧道產生異狀原因的評估以及修復改善設計之重要依據。

The most evident effects caused by external force application, worsening construction material quality or other factors are cracks and water inflow appearing on concrete lining. Techniques such as visual measurement, ground penetration radar, drilling and sampling are still being used for tunnel inspection nowadays. Because these traditional techniques were originally designed to be used for inspection of constructions in open space, efficiency and accuracy using these techniques are not sufficient when they are used to inspect tunnel which is a longitudinal enclosed space. In view of this deficiency and with their long historical background in tunnel constructions, the Europeans have developed an automatic inspection system for this purpose. The system makes use of combined techniques of visual image, thermal image and space scanning techniques. Scanner with 360 degree rotation capability, can very quickly and accurately gather visual image, temperature, and clearance information for the entire length of tunnel. Investigation of the collected data will help to lead us to the reasons of the unusual appearance in the tunnel.
