摘要
文章通过采用数值计算、模型试验和现场试验等研究手段,从静力学、动力学两个方面,对小净距隧道中夹岩的破坏模式进行了研究,得出了小净距隧道中夹岩的破坏始于靠先行洞一侧拱腰位置的结论。
By means of numerical calculation,model test and field test,this paper studied the failure mode of central rock pillar of multi-arch tunnels with small interval from both aspects of statics and dynamics,and the research results show that the failure of central rock pillar of multi-arch tunnels with small interval starts from the position of arch haunch on the side of the advance excavated tunnel tube.
