盾构始发与到达施工是盾构法建造区间隧道的关键工序，也是施工频繁的常见工序。一旦发生事故，将造成较大人员伤亡和经济损失。将失效模式与效应分析（FMEA）法引入地铁盾构始发与到达施工风险评估。通过对该施工工序特点剖析，识别失效模式，制定风险评估标准；通过专家问卷调研，按FMEA法计算风险优先指数（RPN），并对各类风险进行灾害严重性定级；最后，通过对国内地铁施工典型事故案例分析，验证FMEA法评估风险的有效性。
盾構始髮與到達施工是盾構法建造區間隧道的關鍵工序，也是施工頻繁的常見工序。一旦髮生事故，將造成較大人員傷亡和經濟損失。將失效模式與效應分析（FMEA）法引入地鐵盾構始髮與到達施工風險評估。通過對該施工工序特點剖析，識彆失效模式，製定風險評估標準；通過專傢問捲調研，按FMEA法計算風險優先指數（RPN），併對各類風險進行災害嚴重性定級；最後，通過對國內地鐵施工典型事故案例分析，驗證FMEA法評估風險的有效性。

The construction at TBM launching & break through area is a critical and frequent common process of tunneling construction. The accident will result in severe casualties and economic losses. This paper presents construction risk identification and evaluation at TBM launching & break through area based on Failure Mode and Effect Analysis (FMEA). Firstly tunneling construction process features are analyzed, failure modes are identified, and risk evaluation criterions are formulated. Secondly Risk Priority Number (RPN) is calculated according to expert questionnaires, risk-disastrous severity is classified. Lastly the validity of risk evaluation is verified through case analysis of typical metro accidents at TBM launching&break through area.
