断层破碎带地段隧道施工关键技术

Key technologies for tunnel construction in fault fractured zone

隧道施工环境复杂,考虑到穿越断层破碎带过程中的稳定性要求,有必要从断层破碎带的地质状况出发,探寻可行的隧道施工技术。基于此,文章以东天山隧道工程为例,针对断层和破碎带对工程的不良影响,对其施工技术展开了详细的探讨,为顺利穿越断层破碎带提供支持,消除地质灾害等问题。

The tunnel construction environment is complex.Considering the stability requirements during the process of crossing the fault fracture zone,it is necessary to proceed from the geological conditions of the fault fracture zone to explore feasible tunnel construction technologies.Based on this,the article takes the East Tianshan Tunnel engineering as an example,and discusses the construction technology of faults and fractured belts,and provides support for the smooth passage of faulted fractured belts and eliminates geological disasters.
