Analysis Of Subway Construction Safety Accident Based On Dynamic Meta-Network

In China’s rapid economic development,urbanization progress continues to deepen the background,each city more and more attention to traffic planning and development.At the same time,underground traffic in which the status is also getting higher and higher,but in the development of underground traffic,it will inevitably happen some construction safety accidents.Underground traffic can be safe,steady and efficient development,will be directly related to each person’s life and property security,affecting the progress of urbanization,related to China’s social stability and harmonious development.In the context of economic globalization,it will be related to our international political status.Therefore,the study of this subject has irreplaceable significance.This thesis focuses on how to effectively avoid the occurrence of subway construction safety accidents.In this thesis,the dynamic meta-network analysis method is used to establish the node system,and the relevant engineering examples are analyzed to find out the solutions to avoid similar accidents.In this thesis,taking the construction accidents of Hangzhou Metro Line 1 as an example,combined with the theory of the cause of the accident and the microcosmic analysis of the subway construction,after taking full account of the subjective initiative,the personnel,behavior,events and Organization as the node system.Combined with the causes of the accident,background and accident handling report to determine the number of nodes and the relationship between nodes,the establishment of the Hangzhou Metro Line 1 construction safety accident network model.In the analysis of the network map,this thesis uses a random strike and focus on the two strategies,focusing on the strategy to establish the authority of the center,the degree of degree and the degree of close center as a reference index of specific combat methods,and its combat effect A comparative analysis,found an ideal strike strategy,established the importance of the node sort,by effectively monitoring the relevant nodes,that is,the supervision of relevant staff and organizations,and control the behavior of the relevant personnel and organizations,you can effectively avoid or Reduce the recurrence of such accidents.To avoid the subway construction safety accidents to provide new research ideas.
