摘要
考虑到双洞小净距隧道的不同施工方法对隧道围岩稳定性的影响,通过建立了有限元分析模型,针对某开挖间距进行了分析,通过分析某拱顶下沉得出了在Ⅳ类围岩条件下,两隧道的开挖间距宜为30米左右。
Considering the influence of different construction methods on the stability of tunnel surrounding rock,a finite element analysis model is established to analyze the distance between a tunnel.By analyzing a crown settlement,it is concluded that under the condition of郁surrounding rock,the excavation interval between the two tunnels should be30meters.
