摘　　要：在岩溶隧道施工中,回填技术能够通过填补空间增强隧道的整体稳定性,避免潜在的崩塌或沉降风险,封闭溶洞或裂缝,确保隧道内部的干燥和安全。文章探讨岩溶区隧道建设中的回填法施工技术,介绍小型溶洞中的施工工艺及关键技术措施,并结合成功案例总结施工经验,为相关工程提供借鉴。Tunnel construction in karst terrains faces numerous challenges,leading to significant safety concerns during construction.Grouting techniques play a pivotal role in karst tunnel construction,enhancing the overall stability of the tunnel by filling spaces,preventing potential collapses or subsidence,sealing caves or cracks,and ensuring the dryness and safety of the tunnel interior.This paper delves deeply into the grouting techniques used in karst tunnel construction,emphasizing the construction methods and key technical measures in small caves.Additionally,by consolidating construction experiences and successful case studies,the paper aims to offer insights and references for related engineering projects.
