摘　　要：以深圳地铁10号线车辆段出入线单洞三线大跨度隧道为例,在开挖过程中采用三台阶“九洞六步”法进行了施工,提高了施工效率,节省了施工成本和工期,保证了施工质量和隧道施工安全,为类似浅埋大跨度隧道开挖施工提供了参考与借鉴。Taking the large-span tunnel of the third-line at the access lines of Shenzhen Metro Line 10 depot as an example,the three-bench nine-hole six-step method was adopted during the excavation process,which improved construction efficiency,saved construction cost and period,and guaranteed the construction quality and safety.The method provides references for construction of similar shallow-buried large-span tunnels.
