摘要
本文採失效模式與效應分析之風險優先指數法進行專家關鍵評點,以評析潛盾隧道工程各項作業之風險程度,藉以辨識1.潛盾機主體、2.潛盾機出發與到達、3.線形管理、4.土壓平衡式潛盾機開挖管理、5.泥水式潛盾機開挖管理、6.隧道環片、7.背填灌漿、8.防水等流程中,總計209項潛盾隧道施工作業失效因子與對應之一般管制措施。另依評析之風險等級與作業特性,分別納入設計與施工之品管程序予以強化管理效能,符合分階篩除失效因子以達降低風險之全面品質控制精神。
英文摘要
A total of 209 shield tunneling construction failure factors, which include: 1. shield machine, 2.launch and arrival, 3. alignment management, 4. excavation management of earth balance type shield machine, 5. excavation management of slurry type shield machine, 6. segment, 7. backfill grouting, 8. water stop, with their general control measures are identified. Risk Priority Number of Failure Mode and Effective Analysis is adopted to evaluate risks of shield tunneling in order to recognize high-priority risk activities. General control measures of these high risk activities are reviewed throughout the process. According to the principle of the Total Quality Control System, proper actions are required based on each case condition during design and construction stages, respectively.
