摘要

台灣多山且因位處板塊撞擠帶，地質構造複雜。以往不論水利建設、鐵公路建設及水力發電建設等都涉及艱難的隧道工程，這些隧道工程不但在量及質方面，同時在工程技術方面都不斷與時俱進，日新又新，從最早以人工開鑿演進到現代的各種新工法，在隧道史上都可以看到脈絡。本文首先針對與隧道工程關係密切的地質特性作一概略說明，接著列舉多項隧道工程技術的演進過程，最後面臨各種困難地質的對策作一完整的回顧，以期藉由歷史的經驗提供未來隧道工程的借鏡。

Taiwan is a mountainous island and meanwhile located along the tectonic boundary of the Eurasian continental plate and the Philippine sea plate. Therefore, it has a very complicated geological structures and is a severe challenge to tunnelling works. Many national development projects such as water transmission lines, railway and highway projects, and hydropower development projects, involve lots of tunnelling works. Those tunnelling works both size and scale have been increased significantly from time to time. And the construction techniques have also been improved substantially from project to project. For instance, in the early stage, tunnel excavation was carried out by hand while nowadays is carried out by tunnel excavation machines. In this paper, the geological features, which are closely related to tunnelling works are outlined. Then, some technical developments such as support systems etc. are presented. Finally, handling of difficult ground is illustrated. It is hoped that the experience learned in the past can be utilized in the similar projects in the future.
