摘要
研究目的:近年来地铁盾构施工安全事故逐渐增多,给国家、行业、企业和个人带来严重损失。为预防地铁盾构掘进施工安全事故,本文基于"人-机-环境"系统工程方法构建地铁盾构掘进安全影响因素分析框架,综合运用文献分析、案例分析和专家访谈等方法系统识别安全关键影响因素;应用DEMATEL-ISM方法剖析因素间影响关系,构建地铁盾构掘进安全事故致因模型;选用HF盾构区间开展案例研究,验证事故致因模型的适用性。研究结论:(1)地铁盾构掘进安全影响因素可系统识别为人员类、机械设备类和环境类等安全影响因素;(2)地铁盾构掘进安全事故致因过程可用5级安全事故致因模型解释,其中致险作业情境是安全事故发生的直接原因;(3)安全预案、安全检查和安全技术作业是现场安全管理的重点;(4)本文研究的安全事故致因模型可用于指导地铁盾构施工安全管理。
Research purposes: Safety accidents in subway shield construction have increased in recent years and they caused huge losses to government,industry,enterprise,and individuals. To prevent the safety accident in subway shield construction,this paper investigated the safety impact factors and accident causation model. We proposed an analytical framework for safety impact factors using system engineering method of " human-machine-environment" and identified key safety impact factors based on literature review,case analysis and expert interview. The safety accident causation model was constructed based on DEMATEL-ISM method. And then,HF sub-project was chosen for case study to test the applicability of the safety accident causation model.Research conclusions:(1) The safety impact factors in the subway shield construction can be systematically identified as personnel,mechanic-equipment and environmental impact factors.(2) Safety accident causation of subway shield construction can be interpreted by five-tier system model,of which accident-causing situations are the direct factors.(3) Safety plan,safety inspection and worker safety competencies are the pivot nodes.(4) The causation model proposed in this research can guide the safety management during subway shield construction.
