摘　　要：对于无法提前在隧洞出口位置修建拆机硐室或滑行硐室的TBM独头掘进项目,为了能够快速、经济的出洞施工TBM拆机设施,建议采用在TBM尾部设置支洞供人员设备率先出洞施工拆机设施的方式。文章以西藏某公路隧洞独头掘进双护盾TBM施工隧洞项目为例,从TBM停机位置选择、支洞口钢管片设计、安装、拆除以及支洞施工等角度介绍了TBM尾部支洞施工技术。For TBM single-heading excavation project that can not be built in advance at the outlet of the tunnel for the dismantling chamber or sliding chamber,in order to quickly and economically carry out TBM dismantling facilities for tunnel exit construction,it is suggested to set up support adit at the rear of the TBM for personnel and equipment to exit the tunnel and carry out dismantling facilities.Taking the construction of a tunnel project using a single head excavation with double shield TBM in a certain highway tunnel in Tibet as an example,the article introduces the construction technology of the rear support adit for TBM from the perspectives of TBM stop position selection,design,installation,and dismantling of the steel pipe segments at the support adit entrance,and support adit construction.
