Research On Construction Safety Management Of Metro Station Engineering Based On Drilling And Blasting Method

Urbanization promoted the rapid rise of metro construction,the metro station is a key link in the process of metro construction.Most of the construction of the metro station are built in the city downtown.Station buildings exert a tremendous influence on the city building structures,underground pipelines,ground transportation and people’s lives exert a tremendous influence.And drilling-blasting method of metro station construction is complex;involves a wide range urgent need to carry on the safety management.This paper uses the method of the system safety analysis,combining safety management theory and mathematical models,discusses the safety management of drilling-blasting method of metro station,the main researches are as follows:(1)Based on the system security theory,expoud the basic theory of the safety management of drilling-blasting method.It describes the composition of the metro station,classification and construction methods;discourse the construction technology,the line of construction and the feature of construction safety management;clear the content of the safety management of drilling-blasting method.It discusses its applicability in the construction of the metro station.(2)Using the risk management failure and tree analysis to identify the risk factors for drilling-blasting method.From people, objects, environment,management begin to build drilling and blasting method of metro station construction management failures and dangerous trees,and its qualitative analysis, based on the analysis results covering one subsystem,physical subsystem, environment subsystem,management subsystem the drilling and blasting method of metro station construction safety management evaluation system.( 3) Through the triangular fuzzy number and OWA weights applicability of methods to determine the scope of application of the two methods of empowerment, the combination of both the importance of the assignment of the evaluation system;considering the ambiguity of human thinking and individual metrics inconsistency,combined CUOWA operator constructed by drilling and blasting metro station construction zone safety management assessment model number, in the form of interval numbers for a comprehensive assessment of the evaluation system.(4)Combined with Qingdao metro line 3 metro station project, drilling-blasting method of construction safety management evaluation system and drilling-blastingmethod metro station safety management evaluation model is applied to the engineering practice of the metro station, according to the evaluation results to determine the station construction is important to control the risk factors, in combination with drilling-blasting method construction process for drilling-blasting method of metro station project construction safety strategy.
