The Hazard Identification And Evaluation Research For High-rise Buildings In Construction Stage

China's economic development is getting faster and faster,the differences in the economic level of different regions,so that the development of the construction industry also showed a significantly different level.High-rise building project is the focus of modern construction industry,how to maintain the construction of high efficiency,reduce the incidence of construction accidents,modern construction safety management is an important core issue.As the high-level construction projects with natural hazards,the project is always with a dangerous source,and in the construction process,this risk is also dynamic changes,to fundamentally eliminate the occurrence of security incidents,it is necessary to high-rise building construction hazard The existence and incentives for deep-seated analysis,the greatest extent possible to reduce the possibility of accidents for the construction workers to provide the most basic safety and security measures.According to the current situation of domestic high-rise building construction,in the complex and changing environment,the existence of dangerous sources in the theoretical analysis of change,through the identification and discussion of different types of dangerous sources to study the root causes of high-rise building accidents,Tree principle to carry out the basic type of research,to explore high-rise building safety evaluation index design pattern.Through the LEC evaluation method,the weight value of the hazard index in the whole safety accident is calculated,and the theory and model support for the identification and evaluation of the danger source at the high level construction site are provided scientifically.The evaluation model of the construction site is evaluated by the combination model of the accident tree method,which reflects the reasonable safety of the construction site as a whole and lay a good foundation for the future construction.
