文章以永宁高速公路A14合同段危险源辨识与控制为背景,引入海因里希法则,采用经验分析法和作业条件危险性评估法2种安全评价方法,首先对整个标段危险源辨识和评价做概述,并以五福亭特大桥为例具体说明,对该桥施工危险源进行辨识和危险性评估。然后分析A14合同段风险控制措施,以期降低事故发生概率,促进项目施工顺利进行,为山区高速公路施工危险源辨识与风险控制提供参考。
Taking the identification and control of Dangerous Source of A14 Contract Section of Yongning Expressway as the background, this article introduces Heinrich’s rule, adopts two kinds of safety evaluation methods of experience analysis and operational condition risk assessment, and first identifies and evaluates the hazard source of the whole section To make an overview, and to Wufu Ting Bridge as an example to illustrate the danger of construction of the bridge identification and risk assessment. Then, the risk control measures of A14 contract section are analyzed in order to reduce the probability of accidents and promote the smooth construction of the project, so as to provide references for hazard identification and risk control of mountain expressway construction.
