Study On Construction Risk Control Of Beizhuyan Super-large Bridge Around City Expressway

In recent years,infrastructure construction has become an important means to drive the national economic development,especially the rapid development of infrastructure projects represented by high-speed railway,intercity railway,expressway and airport.In bridge construction,restricted by subjective and objective factors,it is easy to have many safety accidents such as collapse,capsize,mechanical injury and falling from high places,which cause serious casualties and property losses,and also bring serious adverse effects to construction enterprises.Based on the qing rong inter-city railway north pearl rock the highway-ring around across large bridge as an example,using the literature survey method,analytic hierarchy process(ahp),and index system method,the security risks that exist in the process of bridge construction for effective identification,in view of the risk identify,by adopting the method of structure analysis theory of scientific evaluation damage degree and the size of security risks,and to optimize the safety organization structure,improve the safety management process,improve the safety management system,bridge internal stress monitoring,BIM information management platform,to reduce and control the purpose of security risks,guarantee the project construction and the safety of the workers.The specific research contents and tasks are as follows:(1)Based on the research of related bridge construction projects at home and abroad,this paper analyzes the safety risks of bridge construction,and briefly introduces the research methods and research contents used in this paper.(2)Combined with the situation of beizhuyan super large bridge project,the main risk factors of safety risk in the construction process are analyzed in detail.(3)According to the actual engineering cases,the expert investigation method,analytic hierarchy process and index system are used,combined with the stress detection data analysis,to carry out comprehensive analysis,identify,evaluate and analyze the construction safety analysis of beizhuyan super large bridge,and put forward improvement measures and relevant suggestions according to the specific risks of the project.(4)Manage the manpower,safety and intelligence in the construction process,and combine the stress monitoring data and bim5 d intelligent management platform to find out the weak links in the construction for key quality monitoring.
