摘　　要：针对广州地铁小北站洞群具体情况,研究提出了城市密集建筑区明暗挖结合立体交叉洞室群地铁车站的合理施工顺序,并进行了数值模拟计算分析和现场监测。现场变形控制指标和现场测试数据表明,此方法在整个施工过程中是安全稳定的,对类似工程有一定借鉴意义。According to a small North Railway Station of Guangzhou Xiaobei Metro-station, it is suggested that reasonable construction sequence about tunnels crossing in space and constructed by cut and cover method and underground excavation in the city＇s densely built-up areas. The numerical simulation analysis and field monitoring are carried out. On-site deformation control index and field test data show that this method is the security and stability throughout the construction process, which have a certain referential significance for similar projects.
