| 摘要(中) |
本研究選定台灣中部砂頁岩互層及卵礫石層兼具之國道6號埔里隧道為研究對象，匯集其開挖記錄、控制記錄、以及地質構造等資料比較於高鐵八卦山卵礫石層隧道工程，以探討出各項影響隧道施工進度及工程管理的因素，並題出建議改善，以提供爾後類似地質隧道工程之施工參考。 綜合本研究結論，摘要重點如下： 1.地下水為影響隧道施工進度之重要因素，尤其地下水常為卵礫石施工成敗之關鍵因素，砂頁岩互層阻水性雖佳，但砂岩層形成地下水通路時亦可能影響開挖面穩定，因此二種隧道施工前均應快速有效降低水位，以利後續施工。 2.隧道頂拱上分覆蓋層厚度較薄時，隧道施工對地表造成直接影響，一般覆蓋層厚度小於開挖寬度2至3倍時，即需考慮淺覆蓋之支撐問題，八卦山隧道於洞口段使用管冪工法，灌漿改善地盤，比較於埔里隧道未施作適當之改善措施，以致埔里隧道洞口段造成支堡入侵支撐斷面，八卦山隧道顯能達成安全施工之目的。 3.八卦山隧道採用濕式噴凝土施工，以噴漿臂代替人工操作噴嘴管作業，較台灣傳統乾式噴凝土施工效果較佳。 4.在全能工班之施工管理，八卦山隧道採以時段為交班界面比較於國道6號埔里隧道採傳統輪進方式，更能消弭消置時間。 |

| 摘要(英) | A
comparison study was conducted in this research to investigate
the difference in tunneling engineering between gravel tunnel
and alternative gravel/shale tunnel using two major highway and
railroad tunnels in central Taiwan . The excavation procedure,
control/monitoring, and geological investigation data were
collected and studied to investigate the major factors affecting
the effectiveness of tunnel excavation procedure and
construction management for the selected tunnels. As a result of
the study, conclusions were drawn to provide suggestions for
future better tunneling engineering in similar geological
conditions in central Taiwan . The results of the study were summarized as the following: (1) Although shale exhibits better water-sealing characteristics, the seepage flow channels formed within the shale layer may jeopardize the stability of the tunnel excavation. Effective dewatering/drainage systems before and during excavation are necessary for both tunnels in the study to maintain adequate stability for the subsequent construction activities throughout the tunnel excavation process. (2)The use of ground supports such as pipe-curtain technique, or jet grouting is necessary for gravel tunnel, especially in the opening section, when the depth of the over-burden is smaller than 2-3 time of the excavation width. (3) The wet shot-crete can be used for the lining to achieve significant greater effectiveness for gravel tunnel than that by the traditional dry shot-crete. (4) The scheduling management using full capacity rotation resulted in much less idle time in tunneling process than using the traditional rotation as employed in the alternative shale/gravel tunnel. |
