河南理工大学本科毕业设计（论文）CONSTRUCTION SAFETY EVALUATION OF CONSTRUCTION GROUPAbstract：With the improvement of society and science technique, high building of Construction Engineering Group 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, high technical requirements and so on. According to the reason, this paper studies safety evaluation of Construction Engineering Group in the process of building of high-rise construction. It is known that construction risks caused by high-rise building construction of Construction Engineering Group are the deep depth of foundation digging, the great height of work place, the much crossover work, the long time for a project. According to these factors, this paper will identify danger resource using 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. 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 established the index system of the construction safety evaluation and pointed out the prevention measures, which can forecast and prevent to the accidents of high-rise construction for the safety of high-rise construction.
