The Metro Engineering Construction Safety Accident Cause Factorand Countermeasures Research

With the acceleration of the urbanization process,more and more people into the city,the urban population growth at the same time,traffic congestion problems gradually highlighted,the major cities have invested in subway construction,through the subway to ease the urban traffic pressure.In the large number of subway construction process,casualties,property damage,social impact followed.Subway construction safety accidents not only to people's lives and property caused significant losses,but also had a bad impact on society.Based on the analysis of the causative factors of the accident,the paper puts forward the corresponding preventive measures,and it is of great significance to strengthen the construction safety of the subway project.In this paper,the causes of the accident caused by the subway project are analyzed systematically.Management,reduce the incidence of accidents has important practical significance.The main research work of this paper is focused on the following aspects:First,on the basis of the relevant theoretical research at home and abroad,combined with the actual situation of China's subway project construction,put forward the theory of accident cause suitable for the safety management of subway project construction.The analysis of the distribution of 142 accidents in different times,space and accident types in 142 cases of subway engineering construction accidents from 2003 to 2016 was analyzed.The statistical analysis showed that the subway engineering construction safety accident In the time,the occurrence of space has a certain regularity,subway construction safety accident main types of accidents:collapse accident,object blow,faling in height.Thirdly,summed up the subway engineering construction safety accident causes factors,including personnel,environment,management,equipment,materials and other five aspects,and then use causal analysis from the staff,the environment,management,equipment,materials and other aspects of specific analysis Collapse of the accident,the impact of objects,the high fall of these three types of accident-specific factors,to identify the subway project construction safety accident causes factors.Fourthly,according to the factors that identify the safety accidents of the subway project construction,the evaluation index system is constructed.Through the expert scoring,the weights of each index are determined by AHP method,and then the fuzzy comprehensive method is used to evaluate the index synthetically.According to the evaluation results,Corresponding precautions.In this paper,based on the construction project of Yuejiazhai station on the subway line 5 of Xi'an subway station,this paper applies the theory and evaluation method of the safety accident of the subway project construction,and validates its validity and applicability.The research results of this paper have theoretical and practical value for analyzing the causes of safety accidents in the subway project construction,reducing the accident rate and the loss caused.
