摘　　要：通过模型试验对软弱围岩下3孔小间距浅埋暗挖隧道的地表沉降控制技术进行了深入研究。结果表明:不同的预加固强度、开挖进尺,对隧道的地表沉降、围岩压力、洞周位移都有很大影响。The controlling measures for ground surface settlement of three little distance parallel shallow embedded tunnels in weak surrounding rock have been studied. The results show that the different engineering measures have obvious influences upon the ground surface settlement,the surrounding rock pressure, and convergence displacement.
