建筑工程安全的风险识别及评价方法研究

建筑项目安全风险管理主要分为 3个阶段进行 :风险识别阶段 ;风险评价阶段 ;风险决策阶段。笔者主要对整个建筑工程项目建设过程中安全风险管理的前两阶段进行了探讨 ;在分清不同阶段的风险管理职责的基础上 ,提出了应用性较强的“子系统风险管理模型” ;进行了相关的实例分析 ,证明了其在风险的识别和评价阶段的适用性 ;并在风险评价方法中 ,合理制定了对不希望发生事件的发生概率和结果严重度的评价标准 ,为建筑安全风险的科学评价提供了依据

Study on Method for Risk Identification and Evaluation in Construction Safety

The responsibilities and functions in project safety risk management for designers and contractors are discussed. Generally the process of risk management is divided into three stages: the risk identification, evaluation, and decision making. The former two are mainly the designer's responsibility, for which a model of sub-system risk management approach is put forward. The model is exemplified and analyzed with real cases. The feasibility in risk identification and evaluation period is proved. The evaluation criteria of occurrence probability of unexpected events and severity of outcomes are rationally set up in evaluation method, which provide the scientific basis in risk evaluation of the construction safety.
