Abstract:	捷運系統工程，以其屬於都會區交通建設之特性，若不慎發生重大意外事件，其影響層面，幾乎都釀成對社會民生的重大威脅衝擊，所產生業主及廠商損失，也是一時難以估計及彌補，而要最直接有效的減輕或避免工地意外事故的發生，就是要在各個施工階段的施工前，直接針對當下之施工情境進行風險評估，並適時採取預防及矯正之對策，才能夠立竿見影產生效果，但是依目前捷運工程施工情況，施工階段之風險評估僅為各工作面直覺式各自獨立產出風險評估結果，所以，如何建立一個簡單有效之施工階段風險評估模式，是一個當務重要課題。本研究目的是要建立一套捷運工程高施工風險項目之施工階段風險評估模式，而模式建立的目標是要完成一個可在不同施工風險因子條件考量下，進行風險度評估之管理方法，研究架構之衝擊因素評估項目係結合模糊層級分析法(FAHP) 作為尋求權重判定的主要來源，以制定捷運工程風險分解結構(RBS)，再探究國際上符合本國捷運工程使用並廣被接受之風險級距等級評估衡量準則 (Risk Evaluation Criteria)，依波達方程式 (Borda’s Function)修訂建立完整風險評估架構，並選擇捷運潛盾隧道工程施工為實例驗證，藉由捷運文獻探討並彙集捷運工程線上監造及施工管理者的意見，歸納出捷運工程風險評估模式。 Rapid Transit System, which features as a metropolitan public transportation, has great impact on the social and public levels if accidents occur. It is often difficult to calculate and recover the loss caused to the Owner and contractors. The most efficient way to reduce or prevent accidents in construction sites is to take precautionary and adjustment measures. However, under the current Rapid Transit System, the construction risk-assessment is made based on intuition developed from individual working interfaces. As a result, it becomes crucial to establish a simple and effective risk assessment method applicable to different stages of the construction work. The purpose of this dissertation is to set up a construction risk assessment module for the high-risk Rapid Transit System construction items. And the purpose to set up such module is to enable risk assessment management under different construction risk factors. The assessment items for impact factors use the Fuzzy Analytic Hierarchy Process (FAHP) as a main source of weighing judgment to determine the Risk Breakdown Structure (RBS) of Rapid Transit System construction. In addition, the internationally accepted and nationally applicable Risk Evaluation Criteria are being studied and revised with the Borda’s Function to establish the complete structure of the risk assessment structure. A case study on the Tunnel Boring Machine is used here to exemplify the discussion of reference on Rapid Transit System and collection of practical ideas from real executors of Rapid Transit System construction, in order to reach conclusion for the rapid transit system construction risk assessment module.
