【摘要】 大型工程施工中 ,由于施工作业在时间、空间上的分散性、施工技术的复杂性等的影响 ,施工作业存在众多的不安全因素。施工作业人员的人身安全、施工设备以及各种设施经常受到这些不安全因素的威胁。结合大型工程的结构、施工作业特点 ,对施工作业危险性进行动态的跟踪分析 ,得出施工作业危险度在时间、空间上的变化趋势和规律。建立了安全管理的动态危险性指标 ,找出了影响施工作业危险性指标的主要因素和主要作业工序。分析的结果将为施工安全管理提供客观、科学、实时的动态跟踪信息 ,提高施工安全管理的目的性和效率。最后结合某引水工程实例 ,给出了动态安全分析结果以及安全管理建议。更多还原

【Abstract】 The project constructions are usually faced with many unsafe factors that bring great harm to workers and equipment. In this paper, a dynamic safety analysis model was presented using hazard index relating to an activity and overall project in construction. The hazard index was used to describe the unsafe level of single activity, and the overall unsafe level of the construction was described by the accumulation of the hazard index for all activities being conducted simultaneously in the construction. The results then can be used to provide the construction managers with useful information. At the end, an example was analyzed with this method.更多还原
