摘要
随着社会的不断发展进步,各种用途的隧道不断修建,隧道工程施工技术水平也不断提高与发展.我国地铁修建方法已由最初单一的明挖法发展到现在的明挖、盖挖、浅埋暗挖及盾构法等多种方法并存,极大地推动了地下工程的快速发展.实践证明,选择一种合理的施工方法是工程成败的关键.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18 m的监测数据作为依据,总结经验,指导施工.
With the continuous development and progress of society,tunnels for various purposes have been built constantly,and the construction technical level of tunnel engineering is also improving and developing.The construction methods of metro in China have developed from the original single open-cut method to the coexistence of open-cut,cover-up excavation,shallow-buried excavation and shield tunelling,which have greatly promoted the rapid development of underground engineering.Practice has proved that choosing a reasonable construction method is the key to the success of the project.The construetion of shallow-buried excavated tunnels in the rear wiring of the Airport Station is conducted by the“double-sided heading method".In this paper,the author briefly introduced the construction technology of temporary support dismantling by“double-sided heading method",and summed up experience to guide the construction based on the monitoring data of the first 18 m section.
