Research On Safety Assessment And Forecast Of Building Constrution

With the rapid development of our country,the construction industry has also ushered in the golden era of development.However,the characteristics of construction, construction site, there is always a lot of safety problems, various unstable factors at any time may lead to accidents.Construction safety research is very important.In this paper, based on the national construction safety accident data, analysis, construction safety accident type, accident location, heigh-rise building construction of the"five injury"caused by conduct analysis, for example, the use of fault tree analysis to analyze the accident to a height fall. The main reason and the key to prevention. Then a pre-risk analysis(PHA) and operating conditions of the risk evaluation method(LEC) based on the establishment of the fuzzy comprehensive evaluation method(FCE) as the main body of the safety evaluation method; based on the national data on construction safety accident casualties, the use of AR models, trend extrapolation and gray system theory in 2008 to predict casualties in the accident; and real value compared to elect a better forecasting methods, be amended. The use of modified model predicted the building of security incidents in 2009 the number of casualties, and the enterprise with the extraction of accident casualties validation of predictive models. Finally, a construction company to conduct an overall assessment of security conditions and forecasts made effective safety precautions.
