摘　　要：结合高速公路隧道洞口浅埋段塌方冒顶处治实例,通过数值模拟确定山体的稳定性,排除了滑坡的可能性,并利用隧道二衬结构强度验算结果提出了适用于本项目塌方段的二衬结构方案,为最终方案的确定提供了依据;处理方案需综合考虑施工现状和注浆加固效果;为了后期运营期间隧道的结构安全,可对结构的应变、断面收敛等开展实时在线监测。通过后期监控量测数据反馈,该方案取得了较好的成果,相关思路及研究结论可供借鉴和参考。This article takes the study of the treatment plan for landslip and roof fall in the shallow buried section at the entrance of highway tunnel as an example.The stability of the mountain was determined through numerical simulation,excluding the possibility of landslides.And based on the strength calculation results of the tunnel secondary lining structure,a secondary lining structure scheme suitable for the collapsed section of this project was proposed,which provided a basis for the determination of the final plan.The treatment plan needs to comprehensively consider the construction status and grouting reinforcement effect.In order to ensure the structural safety of the tunnel during later operation,real‑time online monitoring can be carried out on the strain and section convergence of the structure.Through the feedback of monitoring and measurement data in the later stage,this plan has achieved good results,and the relevant ideas and research conclusions can be used for reference and guidance.
