江海盾构隧道施工风险分析与评价

Risk Analysis and Evaluation on Construction of River and Sea Shield Tunnel

对国内江底、海底泥水盾构隧道施工风险进行了详细全面的分析,指出施工风险可能对盾构机械和施工人员、工程质量、工程结构带来的危害,并对风险进行了评价。结合国内隧道施工事故的实例,阐明隧道施工风险发生后果的严重性,对盾构隧道施工风险控制具有指导意义。

Detailed risk analysis was fully made on slurry shield tunneling construction in fiver bottom and sea bottom in China, construction risk to constructors, engineering quality and engineering structure were reminded and evaluated. According to the field case, severity of tunneling construction accident was clarified, which has instructive significance to control tunneling construction risk.
