Study On Safety Evaluation System Of Super High-rise Building Construction

At present,the super-tall buildings are developing rapidly around the world.In China,the golden period of the development of super high-rise buildings will be ushered in.However,at present,China's super-high-rise building construction safety management still has many deficiencies.In this paper,the construction process of safety evaluation system in the safety management of super high-rise building construction is studied in depth.First,the concept and theory of super high-rise buildings and safety assessment are studied:(1)research the definition of super high-rise building,select the object to be studied in this article;(2)The method and train of thought of constructing the evaluation index system;(3)Research on safety risk assessment methods,and in view of the shortcomings in the evaluation method and the complicated calculation,put forward some improvement methods to achieve the purpose of reducing calculation and reducing errors.Second,according to the research,develop the safety evaluation index system of super high-rise building construction:establish the index system through the combination of safety risk identification and accident tree analysis.The safety risk identification method is used to identify the safety risk of super high-rise building construction and the accident tree analysis method is used to analyze the accident tree of high-risk safety risk accidents.Summarize and summarize the underlying events of the six accident trees constructed,and establish the index system of safety evaluation of construction of super high-rise buildings,contains 8 first-level indicators and 63 second-level indicators.Thirdly,using fuzzy AHP to analyze and calculate the safety risk of high-rise building construction projects.At the same time,the preparation of the calculation based on visual basic weight calculation and safety evaluation software.Fourthly,take a construction project for a super high-rise building under construction as an example to evaluate its safety.The results of the safety evaluation of the example project have been obtained:the safety of the project is generally controllable,but there are safety risks in fire protection,deep pit construction,scaffold construction and high-altitude operations.Finally,the example construction management unit's safety response measures for the first-level indicators of safety construction risk in the evaluation system verify the reliability of the indicator system and safety evaluation calculation system.In the last chapter,this article explore and forecast the safety evaluation of the more and more complex super high-rise building construction and the development direction of other safety management research.The problems of applying the AHP method to the practical work are complicated and time-consuming Proposed solution to the future ideas.Think:The future research will be building information and artificial intelligence applications as the main direction.
