Abstract
In the process of tunnel construction, if large-deformation occurs in high geostress soft rock, it will likely cause geological disasters. This situation will not only seriously affect the smooth progress of tunnel construction, but also cause serious safety threat to the construction personnel. Therefore, with the continuous growth in the number and scale of tunnel construction in recent years, the construction technology for high geostress soft rock with large-deformation has begun to receive more and more attention from the society. Based on this, this paper takes an actual project as an example to analyze the specific application of the technology in order to improve the construction effect and avoid the damage caused by the large-deformation of the high geostress soft rock.
