高层建筑施工安全一直以来都是我们关注的话题。目前，国家越来越重视各个生产行业的建筑施工安全，尤其对建筑行业的建筑施工安全监管力度越来越大，这使得建筑行业的建筑施工安全生产越来越规范。本文针对某高层建筑施工现场的建筑施工安全状态，进行危险因素辨识。在经过对各种建筑施工安全评价方法进行对比后，采取作业条件危险评价法对施工单元中的危险因素进行分析，得到施工单元中每个危险因素等级。危险因素主要包括高处坠落，物体打击，坍塌，起重伤害，触电，车辆伤害和机械伤害等。根据危险因素等级的高低，选择对危险等级最高的高处坠落危险因素进行事故树分析，找出导致事故发生的根本原因。然后参考“三E对策”中的建筑施工安全管理、建筑施工安全技术和建筑施工安全教育等方法，有针对性的提出一些建筑施工安全整改措施。基于上述分析，达到改善长江大桥施工现场建筑施工安全状态的目的。

    High-rise building construction safety has always been our concern topic. At present, more and more national attention to construction safety of the various production sectors, especially the construction industry construction safety supervision more and more, which makes the construction safety building industry production more and more standardized. In this paper, construction safety status of a high-rise building construction site, to identify risk factors. After a variety of construction safety evaluation methods were compared, taking on risk assessment of working conditions of the construction unit in the risk factors were analyzed to give the construction unit for each level of risk factors. The main risk factors include falls, against objects, collapse, lifting injury, electric shock, injury and vehicle and other mechanical damage. According to the risk factors of high and low levels, the choice of the highest risk rating falls risk factors fault tree analysis to identify the root cause of the accident. Then refer to the "three E measures" in construction safety management, construction safety and construction safety education techniques and other methods to make some targeted construction safety corrective actions. Based on the above analysis, to achieve the purpose of improving the state of the construction site construction safety Yangtze River Bridge.
