摘要
基于TBM(Tunnel boring machine全断面隧道掘进机)隧道工程不良地质开挖条件,探讨了围岩岩性、断层、挤压、洞壁及掌子面开挖不稳定性对于设备选型、尺寸制约性的影响,针对不同案例,提出了面临不同施工条件的建议和措施。
Based on the unfavorable geological conditions of TBM excavation,this paper discusses the impact of the surrounding rock,fault,extrusion,stability of excavation,tunnel wall and instability of excavating face on the selection of equipment type and size,presenting the special difficulties faced with TBM excavation and giving proposals and measures for different circumstances.
