摘　　要：随着城市地下工程的不断发展进步,各种用途的隧道不断修建,隧道施工技术水平也不断提高与发展。这也使城市地铁的建设更加复杂,相较于传统以明挖法为主的施工方式,目前地铁隧道施工普遍会将明挖、盖挖、浅埋暗挖等多种方式结合进行施工,极大地推动了城市地下轨道交通工程的快速发展。实践证明,选择一种合理的施工方法是城市地下轨道交通工程成败的关键。西安市地铁14号线机场站站后配线浅埋暗挖隧道采用“双侧壁导坑法”进行施工,本文简要介绍了双侧壁导坑法临时支撑拆除的施工工艺,并以首段18m的监测数据作为依据,总结经验,指导施工。With the continuous development and progress of urban underground engineering,tunnels for various purposes are constantly being built,and the level of tunnel construction technology is also constantly improving and developing.This also makes the construction of urban subways more complex.Compared with the traditional construction method mainly using open cut method,the current subway tunnel construction generally combines various methods such as open cut,cover cut,shallow buried and underground excavation,greatly promoting the rapid development of urban underground rail transit engineering.Practice has proven that choosing a reasonable construction method is the key to the success or failure of urban underground rail transit projects.The shallow buried and underground tunnel behind the airport station of Xi'an Metro Line 14 is constructed using the"double side wall guide method".This article briefly introduces the construction technology of temporary support removal using the double side wall guide method,and summarizes the experience and guides the construction based on the monitoring data of the first 18m section.
