施工人员安全能力包括感知能力、判断能力和响应能力。地铁施工中当危险迫近时,施工人员只有正确感知危险、判断危险以及采取正确措施响应危险,才能安全的完成施工。地铁施工人员的感知能力,是判断能力和响应能力的前提。在安全感知能力和项目反应理论(IRT)研究的基础上,通过问卷调查对施工人员安全感知能力进行测定与评价,并对调查问卷的问题进行区分度和难度参数分析。这将有助于提高地铁施工人员安全能力,促进安全管理水平,避免事故发生。
Construction personnel safety capabilities include perception, judgment and responsiveness. Subway construction when approaching danger, construction workers only correctly perceived danger, to determine the danger and take the correct measures to respond to the danger, in order to safely complete the construction. Subway construction staff’s perception, is to judge the ability and responsiveness of the premise. Based on the research on safety perception and project response theory (IRT), the safety awareness of construction workers is measured and evaluated through questionnaire survey, and the discrimination and difficulty parameters of the questionnaire are analyzed. This will help improve the safety of subway construction workers, promote safety management and avoid accidents.
