摘要
为提高深基坑工程施工安全风险管理水平,解决施工过程中安全风险因素众多且关联关系复杂、安全系统稳定性差的问题,基于文献识别出21项深基坑工程施工安全风险因素,并分为人员因素、物料因素、环境因素、管理因素、技术因素五类;通过解释结构模型(ISM)建立深基坑工程施工安全风险系统,共分为5个层级,结合系统结构将安全风险因素以紧急度分为3类;通过交叉影响矩阵相乘法(MICMAC)分析各因素参数,结合中心度将安全风险因素以重要性分为3类;根据紧急度和中心度建立安全风险等级划分标准,将安全风险因素划分为3个等级,从而提出针对性应对策略和措施,以辅助深基坑工程施工安全管理决策。
In order to improve the safety risk management level of deep foundation pit engineering construction,solve the problems of many safety risk factors and complex correlations in the construction process,and poor stability of the safety system,this study identifies 21 construction safety risk factors of deep foundation pit engineering through the literature,and divides them into five categories:personnel factors,material factors,environmental factors,management factors,and technical factors;the construction safety risk system of deep foundation pit engineering is established by explaining the structural model(ISM).The system is divided into 5 levels.Combined with the system structure,the safety risk factors are divided into 3 categories according to the degree of urgency;the parameters of each factor are analyzed by the cross-influence matrix multiplication method(MICMAC),and the safety risk factors are divided into three categories according to the importance combined with the centrality;according to the urgency and centrality,the safety risk classification standard is established,and the safety risk factors are divided into three levels,so as to put forward targeted coping strategies and measures,and assist the safety management decision-making in deep foundation pit engineering construction.
