摘　　要：公路隧道的施工是根据某些地理环境选择的施工方式,以让两条公路顺利衔接,但其施工时经常会遇到软弱围岩,它会增加施工的难度,影响工程质量,同时也会增加工程的安全隐患。故立足于软弱围岩的施工,分析保证施工安全的措施。The construction of highway tunnels is based on the construction method chosen according to some geographical environment so as to make the two roads connect smoothly. However, the construction often involves weak surrounding rock, which will increase the difficulty of construction and affect the quality of the project. Meanwhile, will also increase the safety hazard of the project. Therefore, this article is based on the construction of weak rocks, analysis of construction safety measures.
