基于工效学的施工危险源识别模型

Research on the Model of Construction Hazards Identification based on the Ergonomics

施工生产的工效学系统分解为施工主体、施工条件、施工对象、施工环境四个子系统,是施工安全的一级影响因子,它们可以继续分解为多级细分因子。施工危险源为施工工效学系统因子中,由于因子的不适应或者不适用,引起施工安全绩效下降的因素。注目于危险源识别和能力提高,构建出施工危险源识别过程模型,并解释模型的具体应用。

Construction production system breaks down into four subsystems according to ergonomic principle： construction team, construction conditions, object-engineering, and engineering environment, these are regarded as the primary ergonomic factors for construction safety. Every one of them can be broken into multi-class sub-factors. If any one of the sub-factors does not correspond with the others, or is unapplicability, construction safety performance will go down, then it is defined as the construction hazards. Focus on hazard identification, the model to process of identifying construction hazards is structured, and application of the model is also discussed.
