Research On Safety Assessment Of High-rise Construction

With the improvement of society and science technique, high-building developed rapidly in our country. Meanwhile many safety problems have come out in the high-rise construction now, because it has the characteristics which are many layers, much workload, complex program and so on. According to the reason, this paper studies safety assessment in the process of building of high-rise construction. It is known that he deep depth of foundation digging, the great height of work place, the much crossover work, the long time for a project of accident of high-rise construction, so this paper identify danger resource though fault tree analysis methods. Though analyzing many existing construction accidents, we get to know that the major injury modes include the falling from high place, machine injury, crane injury, object beating, electric shock and collapse. These accidents occupy the 70 percents of all accidents. However accidents including the falling from high place, machine and crane injury were the major research objects in this paper. A typical accident of each kind was analyzed by FTA methods. Then qualitative analysis was given. At last, this paper built sound criteria system of risk assessment. Have assessed safety of high-rise construction with fuzzy comprehensive evaluation and built criteria model of safety, which can take measures to the accidents of high-rise construction for the safety of high-rise construction.
