不良地质条件下隧道施工方法探讨

不良地质条件下隧道施工难度较大,为了保证隧道施工安全和工程稳定性,必须制定针对性的施工方案。该文以某隧道施工为例,对施工中遇见的岩溶、断裂带、突水突泥、危岩落石和缓倾岩层等不良地质条件进行分析,并基于一定的施工要求和基本原则,制定相应的施工方法,为类似不良地质条件下隧道施工提供技术参考。

Tunnel construction is difficult under adverse geological conditions. In order to ensure the safety and stability of tunnel construction, targeted construction plans must be formulated. Taking a tunnel construction as an example, this paper analyzes the unfavorable geological conditions encountered in the construction, such as karst, fault zone, water inrush,mud inrush, rockfall from dangerous rock, sloping rock formation, and based on certain construction requirements and basic principles, formulates corresponding construction method, is to provide technical reference for tunnel construction under similar adverse geological conditions.
