The Risk Control Of The Limb And Hole In Building Construction Based On BIM

BIM is widely used in the construction industry.It covers from the construction project preliminary planning to design,construction and completion of operation,maintenance and other stages,which covers the whole life cycle of the project.There are some scholars make different angle and depth of research for BIM in the construction of safety management.Analysis the construction safety accidents in China in the past 10 years,limb and hole is the area of frequent occurrence of accidents.The accident risk control has become one of the key problems of the most construction enterprises need to solve.In the law of the People's Republic of China on the 13 th five-year plan for national economic and social development program,with particular emphasis on the safety production and the information development of the two points,the demand of the national development and social progress,so this topic research is to the special requirements for the safety in production and the development of the information platform integration.Therefore,the research emphasis of this paper is on the limb and the mouth of the cave,falling accidents in construction risk analysis and risk control.In the text,setting limb and hole as the research object.It introduces the principle and method of risk analysis,and the three kinds of commonly used methods of risk assessment,using FTA analysis over limb and hole,the accident has carried on the deep analysis,find out 24 kinds of factors which cause of the accident,put forward by preventing overexert,when working with heavy fall,fasten your seat belts and ensure that will not remove the seat belt move the four kinds of form,to a certain extent,can control the limb and the mouth of the cave in falling accident.However,it dissatisfy the rapid development of economy,society,science and technology.So,BIM are used to explore the limb and hole of construction,the accident effectively control.Using BIM,in view of limb and hole on risk identification and analysis of components of construction project based on BIM construct the risk control system,the system consists of risk identification,information storage,labels,definitions,reading and writing,layout,location tracking of five parts.Through the construction of high-rise building project based on BIM limb and the hole in the construction of risk control system,to solve the limb of construction site and the mouth of the hole,personnel in terminal in real-time positioning and risk early warning model,discusses the risk of field edge and the hole in the construction of informatization,the possibility of visualization,automation and efficient control.Therefore,BIM is used to limb and hole in the safety management and risk control to provide more research ideas,solutions and technical support,thus to improve the level of safety management of the entire project.
