摘　　要：某引水隧洞受到工程所在地实际地形、埋深等诸多因素影响,隧道施工时地质情况难以完全准确的预测,针对隧洞掌子面前方不良地质洞段,采用径向注浆、大管棚、超前小导管注浆、初期支护等施工技术措施,有效的避免了因不良地质引起的工程事故,提高施工效率,顺利完成了施工任务,从而为后续的不良地质条件下的隧道施工提供参考。A water diversion tunnel is affected by various factors such as the actual terrain and burial depth of the project location,making it difficult to accurately predict the geological conditions during tunnel construction.For the unfavorable geological section in front of the tunnel owner,construction techniques such as radial grouting,large pipe shed,advanced small pipe grouting,and initial support are adopted.It effectively avoids engineering accidents caused by adverse geological conditions,improves construction efficiency,and successfully completes construction tasks,providing reference for tunnel construction under adverse geological conditions in the future.
