Study On The Safety Risk Control Methods Of Construction About The Panjiayuan West Subway Station In Beijing

Taking the construction of Panjiayuan West Railway Station of Beijing Metro Line 17 as the engineering background,this paper analyzes the disadvantageous factors such as open-cut section construction,undercut section construction,cov-er-cut section construction,lining and so on,such as coordination,intersection,par-allel,three-dimensional operation,interference and so on.On the basis of relevant data and data,aiming at the practical problems,the dynamic optimization control of the safety problems in the whole construction process of Beijing subway construc-tion project is carried out by using the comprehensive integrated optimization tech-nology such as complex system theory and safety control technology,which has important theoretical and practical significance for improving the economic and so-cial benefits of subway projects.Use value.The main contents are as follows:(1)establish a static safety and static target model for subway construction safety risk.Firstly,the Panjiayuan West Railway Station is analyzed to understand its geological environment,surrounding environment,construction technology and methods.On the basis of collecting safety data of similar projects,the potential risk position,accident type and frequency of Panjiayuan West Metro Station are deter-mined by using artificial BPNN intelligent neural network.The risk point,risk type and key control position of the proposed project are determined by using the princi-ple of Hain's Law,and the causes of safety problems are established.Strategic data base,security early warning system and safety early warning response system.(2)establish a dynamic optimization control system for subway construction safety.In the process of subway construction,safety control technology and PDCA cycle management technology are used to establish safety statistical report system and optimize safety control.So that managers can intuitively understand the com-pleted project construction situation,timely summary and analysis of the existing problems and causes,timely statistics of each control cycle of the actual safety data,and comparative analysis,find problems,timely warning,new problems,causes,countermeasures,timely update and optimize the original database system And make corresponding pre control measures to dynamically realize pre control of the next cycle.
