中文摘要 | 雪山隧道為北宜高速公路隧道群中最長的一座隧道,全長12.94公里,雪山隧道位於雪山山脈,穿過經輕度變質之沈積岩層,由於岩層受板塊衝擊影響,造成隧道沿線地質構造複雜,變化劇烈,又藴藏豐沛地下水,致施工期間導坑及兩條主隧道曾發生多次湧水抽坍或受困。雪山隧道依規劃設計期間之調查,隧道全線均位於地下水位之下,為消解儲於岩盤內地下水壓之影響,隧道設計為排水隧道,並於施工階段對雪山隧道湧水問題進行鄰近地區水文調查評估工作及建立隧道開挖施工遭遇地質弱帶湧水抽坍處理機制。此外雪山隧道結構複雜且斷面變化頻繁,致出現整體防水層的功效未臻完善之微量滲水事件,亦已建立因應改善措施處理機制。本文擬就前述經驗與案例深入檢討,期能提供工程界爾後類似案例研討的思維方向。 |
英文摘要 | Hsuehshan Tunnel, 12.94 kilometers long, is the longest tunnel of Taipei-Yilan Expressway. Hsuehshan Tunnel is located within the Hsuehshan Range sub-province, which is composed of slightly metamorphosed sedimentary rocks. The rocks have been folded, deformed and sheared by tectonic activities. Locally large quantity of groundwater inflow and cave-ins were encountered due to very high permeability of the rocks and high groundwater table during tunnel excavation. Hsuehshan Tunnel deeply below the groundwater table is designed as a drainage tunnel. The inflow to the hydrological influence of the neighboring areas was studied, and treatments of cave-ins owing to large quantity of inflow in geological weak zones were established during tunnel excavation. Slight leakage occurred due to the bad working condition and structural complexities of the intersections. The leakage treatments have been established after completion of tunnel lining. The experiences of treatments of cave-ins and leakage are described in delail as references for similar engineering encounters in future. |
