Research And Application Of Risk Evaluation And Visualization Scheme For Building Safety Design

The construction industry is one of the pillar industry in China,frequent safety accidents in construction industry pose a serious threat to the safety of people's life and property,and bring new challenges to the traditional architectural design.It is a serious problem to be solved urgently on how to improve the situation effectively.As many security problem in the design stage of the construction project have been produced,the most effective solution is to prevent and eliminate the security risks from the source of design,so as to avoid the occurrence of safety accidents.This paper is to study the visualization of safety special scheme according to construction safety design,based on the application of BIM technology,to explore how to use BIM technology in the application of special safety scheme visualization,to explore the theory and practice of application of BIM technology in the construction design stage to ensure the safety.This paper studies the correlation between architectural design and construction safety,and surveys more than and 20 domestic construction units and design units by the questionnaire and field interviews.On the basis of investigation,the evaluation model of the dangerous and harmful factors is constructed to evaluate architectural design affecting the construction safety architectural design analysis effecting on four categories of harmful factors are summed up existed in different engineering division in the process of construction,the corresponding risk factors may lead to accidents,and puts forward some suggestions for building safety design can be taken the design stage.Finally,the analytic hierarchy is used to process the architectural design effecting on the harmful factors of construction safety risk by further analysis and evaluation,the degree of various factors influence on the construction safety is sorted,the most dangerous and harmful factors in the architectural design are cleared,provding scientific basis on reducing and avoiding the defective design on the construction safety.This paper also studies the application of BIM technology in the visualization of construction safety scheme,and puts forward the concrete application method.Finally,the specific application of BIM technology in the construction of special security visualization is studied.Combined with the project case,through the BIM modeling and 4D simulation of theconstruction,the dynamic construction of hazardous special engineering is modeled,measures to control the risk of project construction process in the actual factors is adopted,safety information need to be the key link in the corresponding position and the corresponding components,to ensure the safety of attention matters of every step of the operation could clearly communicate with management and on-site construction personnel,so as to control the safety risk,reduce and avoid safety accidents...
