摘　　要：CRD中洞法以其具有施工安全易于控制的特点被广泛用于大跨浅埋暗挖软弱围岩段,深圳地铁10号线凉帽山车辆段出入线隧道三线大断面因其具有浅埋偏压、大跨度、复杂地质条件等特点,设计采用CRD中洞法施工,实际施工步序因实际地质状况、技术水平、施工条件、机械设备等因素影响与设计有较大差异,文中重点介绍三线隧道开挖实际控制情况,供探索、讨论之用。The CRD mid tunnel method is widely used in large-span shallow buried soft rock sections due to its safe and easy to control construction characteristics.Due to its characteristics of shallow burial,large span,and complex geological conditions,the large section of the entrance and exit tunnel of the Liangmaoshan Depot of Shenzhen Metro Line 10 adopts the CRD Zhongdong method for construction.The actual construction steps differ greatly from the design due to factors such as actual geological conditions,technical level,construction conditions,and mechanical equipment.The article focuses on introducing the actual control situation of the excavation of the third line tunnel for exploration and discussion.
