摘要
盾构进出洞施工过程是盾构法隧道施工的事故多发环节。结合郑州地铁1号线工程,提出利用专家调查法评定各工况风险等级,利用层次分析法评定各工况致险因素权重的风险分析方法,对隧道盾构进出洞施工进行了风险分析,提出了相应防范措施,为隧道盾构进出洞阶段的施工风险控制提供了依据。
Based on Zhengzhou Metro M1 line project,the risk analysis method is presented in the paper, which evaluates risk level of working condition using expert investigation method and evaluates weights of the risk factors using analytical hierarchy process. Risk of tunneling machine driving-in and driving-out construction process is analyzed. Risk control measures are put forward based on the results of risk analysis.
