摘  要:随着山岭隧道朝着长度更长,断面更大方向建设,竖井施工作为特长公路隧道的重要组成部分,结合兴业快线(北段)隧道1#通风竖井施工实例,从反井法施工的安全性、高效性及施工过程的环境保护三个方面进行了论述。采用反井法施工有利于增加机械化作业时间,降低人工辅助作业的人身伤害风险,保障了反井施工作业过程中人员及设备安全,同时解决了竖井顶部作业空间有限,弃碴运输困难,影响山顶周围生态环境的问题。With the construction of mountain tunnel towards longer length and larger section,shaft construction as an important part of long highway tunnel,combined with the construction example of Xingye Express(North section)tunnel 1#ventilation shaft,the safety,high efficiency and environmental protection of construction process of reverse shaft construction are discussed.The use of reverse well construction is conducive to increasing the time of mechanized operation,reducing the risk of personal injury in manual assisted operation,ensuring the safety of personnel and equipment in the process of reverse well construction,and solving the problems of limited working space at the top of the shaft,difficult transport of abandoned slag and affecting the ecological environment around the top of the mountain.
