| 摘 要： | 小净距隧道是继分离式隧道、连拱隧道后出现的一种适应性较强的新型隧道形式。采用数值模拟方法,对不同开挖方法在不同净距条件下的中夹岩柱的应力变化进行分析,从而为不同净距条件下宜采取的开挖方法提出合理建议,具有一定的工程参考价值。

| Abstract: | The small spacing tunnel with high adaptability is one of the new type tunnels aiter separated tunnel, multiple-arch tunnel. The numerical simulation is conducted to analyze the diversification of stress of the inter-space rock in the condition of different ways of digging and different clear distance, the rational suggestions about digging methods of the small spacing tunnel is put forward, and some reference to analogous engineering is given. |
