| 中文摘要 | 近年來,臺灣的隧道工程逐漸向東部山區延伸,面臨更多山岳隧道的挑戰,如已完工的臺 9 線蘇花公路改善 計畫及通過環評的安全提升計畫。隧道建設需謹慎評估安全性與穩定性,並兼顧山區水文地質環境,以避免水資 源流失。豐沛降雨和地質破碎導致山岳隧道施工常遇滲水問題,因此,初期調查和出水量預估為相當重要之課題。 地下水在山區中流動主要受到地質結構、重力和壓力的影響,當隧道開挖時可視為岩體應力場的改變或應力重新 分佈,從而導影響水壓梯度與流動路徑,促使地下水向壓力較低的隧道內流動,形成出湧水現象。然而,初期地 質調查受限於調查點位置、數量、機具,一般只能獲致隧道沿線大致之水文地質條件,而隧道於實際開挖通過複 雜水文地質環境時,隧道沿線所遭遇之複雜水文地質條件往往隨著施工階段進行始漸漸揭露,於施工階段期間的 出水紀實數據,除可以提供原始分析相當重要的反饋依據,若能結合山區公路隧道水文地質特徵進行系統性探討, 更可提升水文地質評估模型的真實性與可靠度,本研究藉由相關經驗的歸納,希冀提供隧道工程推動與相關水文 地質評估作業參考。 |
| 英文摘要 | Tunnel construction in Taiwan has expanded into mountainous regions, such as in the Suhua Highway Improvement and Safety Enhancement Projects. These projects face frequent water ingress due to intense rainfall and fractured geology. Groundwater flow, governed by geological structures and pressure gradients, is altered during excavation as stress fields redistribute, often causing groundwater to flow into tunnels. Early hydrogeological investigations are limited in scope, and actual conditions are revealed progressively during excavation. Water inflow records collected during construction provide essential feedback for refining initial assessments. By analyzing these records in relation to geological conditions, predictive models can be improved. This study summarizes relevant field experiences to support future planning and hydrogeological evaluations in mountain tunnel projects. |
