对于山区高速公路,隧道是最主要结构物之一,而且占据的比例越来越高,因此隧道路段的拓宽是改扩建工程安全控制的关键。本文以G76高速漳州至龙岩段HC隧道拓宽工程为依托,从事故成因入手,分析施工安全危险源,采用风险矩阵法和指标体系法对各危险源进行风险量化估测,并针对重大危险源提出工程安全保障措施,做到事前预防、事中跟踪、事后处理紧密结合,保证工程高质、有效、顺利完成。
For the mountain highway, the tunnel is one of the most important structures and occupies a higher and higher proportion. Therefore, the widening of the tunnel section is the key to the safety control of the expansion project. Based on the HC tunnel widening project from Zhangzhou to Longyan of G76, the paper analyzes the causes of accidents and analyzes the sources of construction safety hazards. It uses the risk matrix method and the index system method to quantitatively estimate the risks of all the hazards, and puts forward the measures to deal with the major hazards Project safety and security measures, so that prevention in advance, things in the track, after the close combination of processing to ensure that the project of high quality, effective and successfully completed.
