Research On A Composite Method For Risk Identification And Control Of Building Construction

The construction site is a place where multiple accidents and frequent accidents occur.The damage caused by the construction site has the characteristics of time urgency,chain of accidents,severity of events,difficulty of rescue,and far-reaching impact,and the national economy and social sustainable development have caused tremendous damage.The direct and indirect losses.Although governments and enterprises attach great importance to construction safety and employ a variety of technical means to identify and control construction risks,construction accidents are still not effectively controlled.One of the important reasons for this is construction.Risk identification and hysteresis in control,weak pertinence of control measures,poor accuracy of identification,and backward control methods.In view of the above problems,the paper proposes the use of integrated BIM technology and expert system compound method to identify and control the risk of building construction,in order to effectively reduce the occurrence of construction safety accidents.The main content of the study:(1)Based on the analysis of the existing literature,research reports,relevant building construction and design specifications,the qualitative and quantitative analysis of the construction risk information was summarized.(2)Developed a compound system for risk identification and control of building construction.The system integrates BIM technology and expert system compound system.BIM technology uses visualization,can be coordinated,and can automatically extract part of the construction risk characteristics as the person of the entire system.Machine interface,and expert system of integrated rule reasoning and case reasoningis the way for system to realize risk identification and control.In addition,the logical architecture of the system is divided into data layer,protocol layer,and application layer.On this basis,feature extraction is realized.Risk identification,risk analysis and control functions;(3)Identify and control the risk of deep foundation pits by using the complex system of building construction identification and control.According to the risk of water penetration at the bottom of deep foundation pits,feature extraction,case reasoning,rule reasoning,and risk analysis are performed.The thesis uses the integrated BIM technology and expert system method to identify and control the construction risk.The research has the characteristics of construction process and result visualization.It solves the identification of time lag in the construction risk identification and control,and the identification result is credible.The problems of low level and weak targeted control measures are conducive to obtaining effective control measures and help reduce the occurrence of construction safety accidents.
