Safety Risk Analysis And Control Rearch Of High-rise Building Construction

With the rapid development of urbanization in China,urban land resources are becoming increasingly tight.In order to maximize the use of land resources,high-rise buildings occupy a major position in China’s modern urban architecture.The development of high-rise building technology reflects the progress of human science and technology.At the same time,the construction of high-rise building is a multi-process,three-dimensional cross,continuous operation,long duration and large amount of engineering systems project,the risk factors of production safety are also prominent in the construction process.Based on the risk analysis and the theory of system safety,this paper identifies the risk source of high-rise building construction with the method of fault tree analysis,the fault tree model and Risk Index analysis system of main safety accidents are constructed,and the construction safety risk of high-rise buildings is evaluated by using the method of combination of AHP and fuzzy comprehensive evaluation,draw the corresponding conclusion and control strategy.The concrete research work and achievements are as follows:(1)Based on the analysis of main safety accidents in high-rise building construction,the fault tree model is established.(2)Based on the analysis of the basic events of the fault tree model,a safety risk index analysis system is established,which is based on five factors such as human,material,scheme and technology,management and environment.(3)Through the introduction of AHP,the weight of each index of safety risk factors is determined,and the consistency is checked,and the corresponding conclusions and control measures are drawn by the combination of on-the-spot consultation and investigation.
