Research on Safety Risk Factors of Deep Foundation Pit Engineering Construction Based on ISM-MICMAC
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.
