摘要
潛盾隧道工程涵蓋之施工作業內容及項目繁多,包括潛盾工作井構築、發進及到達鏡面地改、潛盾機製造、環片製造、潛盾發進、潛盾鑽掘、背填灌漿、潛盾到達、聯絡通道開挖…等等,個案因應不同的地質條件、環境限制因素及最新潛盾技術發展等,施工作業項目採用之工法及品管標準亦有不同,且潛盾隧道施工屬於高風險施工項目,因此完善的施工品質管理實為潛盾隧道順利完成的重要因素。本文將先介紹臺北捷運之潛盾品質管理項目及重點,再藉由一捷運潛盾隧道工程案例,針對規劃設計考量、潛盾機製造、潛盾掘進施工、潛盾棄殼到達等課題,探討說明捷運潛盾隧道之品質管理方式,期作為後續類似工程之參考。
英文摘要
Shield tunneling is made up of many construction tasks, such as constructing the shaft, executing grout for launching and arrival of shield tunneling, building a shield machine, producing lining segments, boring tunnels, performing backfill grout, excavating the cross passage, and other tasks. The design consideration and quality management of each work varies according to the various site conditions, external limits, and up-to-date shield tunneling technique for each case. Shield tunneling is in the high-risk construction category. The success of shield tunneling depends on the well controlled quality of each work. In this paper, the key points of quality management on shield tunneling for Taipei MRT are described. Then a shield tunneling case, focusing on the topic of design consideration, shield machine, tunnel excavation, and shield arrival, is introduced and studied. The experiences and the quality management in this case are provided as references for similar projects in the future.
