为了预防和减少安全生产事故的发生,提出一种动态风险分析方法,在有效辨识建筑施工风险关键因素的基础上,定量刻画风险的动态演化趋势,并制定针对性干预策略,为改善建筑企业安全环境提供防控手段。首先,基于文献研究与事故致因理论,从人员、环境、设备、管理4个方面,拓展并建立了包含20个条目的施工风险因素分析框架。其次,结合灰色关联分析(GRA)与解释结构模型(ISM)确定可达矩阵,运用交叉影响矩阵相乘法(MICMAC)筛选施工风险关键因素。最后,基于模糊认知图(FCMs)理论对风险节点权重进行动态推导,通过设置不同单目标的干预场景进行模拟仿真,比较了不同方案对于施工风险的影响程度。研究结果表明:影响施工风险的关键因素包括防护用具使用c,11,,操作行为c,12,,隐患辨识c,13,,安全检查c,43,,安全反馈机制c,44,,现场监管c,46,;项目前期,风险因素权重排序为c,11,>,c,43,>,c,13,>,c,44,>,c,12,>,c,46,;项目推进阶段,c,12,,c,44,,c,46,的权重有所增加,变化速率大小为c,46,>,c,12,>,c,44,,而c,11,,c,13,,c,43,的权重均在减小,变化速率大小为c,11,>,c,43,>,c,13,;项目后期,风险因素权重排序为c,46,>,c,12,>,c,44,>,c,13,>,c,43,>,c,11,;干预效果方面,针对c,11,的干预能在较大程度上影响施工风险水平,以c,46,为对象的干预方案获得的安全收益较差。研究成果揭示了建筑施工风险的动态变化过程,可为企业风险防控策略提供一定的理论依据及决策参考。
To prevent and reduce the occurrence of construction safety accidents, a dynamic risk analysis method was proposed. Based on effectively identifying the key factors of construction risk. The dynamic evolution trend of risk was described quantitatively, and targeted intervention strategies were formulated to provide prevention and control means for improving the safety environment of construction enterprises.Firstly, a construction risk factor analysis framework containing 20 items was established based on literature research and accident cause theory from four aspects: personnel, environment, equipment, and management. Secondly, the accessibility matrix was determined by Grey Relationship Analysis (GRA) and Interpretation Structural Model (ISM), and the key factors of construction risk were screened by Matrix Impacts Cross-reference Multiplication Applied to a Classification (MICMAC). Finally, the risk node weight was dynamically derived based on the Fuzzy Cognitive Maps (FCMs) theory, and the intervention scenarios with different single objectives were simulated to compare the impact of different schemes on the construction risk. The results are drawn as follows. The key factors affecting construction risk include the use of protective equipment (c,11,), operant behavior (c,12,), risk identification (c,13,), safety inspection (c,43,), safety feedback system (c,44,), on-site supervision (c,46,). In the initial stage of the construction project, the weight of risk factors was c,11,>,c,43,>,c,13,>,c,44,>,c,12,>,c,46,. During the project promotion stage, the weights of c,12, c,44, and c,46, are increasing. The rate of change is c,46,>,c,12,>,c,44, the weights of c,11, c,13, and c,43, are decreasing, and the rate of change is c,11,>,c,43,>,c,13,. In the later stage of the project, the weight of risk factors is c,46,>,c,12,>,c,44,>,c,13,>,c,43,>,c,11,. In terms of intervention effect, the intervention for c,11, can affect the level of construction risk to a large extent, while the intervention plan for c,46, has poor safety benefits. The findings of the study shed light on the dynamic change process of construction risk, which can serve as a theoretical foundation and decision-making reference for enterprise risk prevention and control strategies.
