超埋深高地应力TBM掘进岩爆防治技术探究

Exploration of rockburst prevention techniques for TBM tunneling under extremely high overburden and geostress conditions

岩爆防治长期以来都是地下工程施工面临的一项技术性难题,由于其规律难寻、发生突然且危害性极强,不仅严重威胁人身安全,往往还直接决定着工程的成败。本文基于陕西省引汉济渭秦岭隧洞岭南TBM工程岩爆防治实例,重点对该工程施工中岩爆发生规律和危害进行分析,继而阐述针对超埋深高地应力TBM掘进岩爆防治的技术措施,可为类似工程提供借鉴。

Rockburst prevention has long been a technical challenge in underground engineering construction due to its elusive patterns,sudden occurrences,and extreme hazards.It poses a serious threat to personal safety and often directly determines the success or failure of a project.This paper focuses on a rockburst prevention case study from the Lingnan TBM project of the Hanjiang-to-Weihe Qinling Tunnel in Shaanxi Province.It analyzes the patterns and hazards of rockbursts during the construction of this project.Furthermore,it elaborates on the technical measures for rockburst prevention during TBM tunneling under conditions of extremely high overburden and geostress,offering insights that could benefit similar projects.
