摘要

坪林隧道長達12.9km，最大覆蓋深度達720m，沿線地質構造複雜，岩盤破碎並蘊含豐富之地下水，有兩個直徑約12m之主坑及一個直徑約5m之導坑同時施工，故地工技術上之問題，需有審慎之考量與評估。本文先由規劃及設計階段，說明有關地工技術方面，規劃時需考量之基本原則及設計之重點，再與施工階段實際之結果比較，最後並提出若干之建議，以為爾後推動類似重大工程時之參考。

The Pinglin Tunnel, including two main tubes with 12 m in diameter and one pilot tube with 5 m in diameter, is approximately 12.9 km long. The maximum overburden is approximately 720 m and the geological structure along the tunnel is very complicated with large amount of ground water. Therefore the geotechnical consideration is very important and should be carefully studied and evaluated. This paper is to introduce the key issues regarding geotechnical engineering during planning and design stages. The actual results during construction is also interpreted to compare with the anticipative condition in the planning and design stages.
