摘要
对施工安全风险进行精准评估,准确确定风险等级,是制定科学、可行、有效的安全风险控制措施重要前提。本文根据安全风险的后果形式,引入“当量”及相关转换标准对安全风险后果进行量化评估,采用专家问卷法对安全风险的发生概率进行量化评估,然后采用风险矩阵法,实现对大型养路机械施工安全风险的精准评估和等级划分。
Precise assessment of construction safety risk and accurate determination of risk grade are impor. tant prerequisites for formulating scientific,feasible and effective safety risk control measures. In this paper, according to the consequence form of safety risk,"equivalent" and related conversion standards are intro. duced to quantitatively evaluate the consequences of security risk, and the expert questionnaire method is used to quantitatively evaluate the occurrence probability of security risks,and then the risk matrix method is used,thus the precise assessment and classification of construction safety risks of large road maintenance machinery are realized.
