摘　　要：结合蕉溪岭隧洞工程塌方情况,讨论塌方的处理方法、施工进度及资源投入。利用有限元分析软件FLAC3D对塌方处理过程中采用的超前小导管注浆方案进行仿真模拟,并与现场监测数据进行对比发现,现场监测数值均比仿真模拟数值要大,数值仍在正常偏差范围内,进一步验证了超前小导管注浆方案简单快速和安全经济的特点。Combined with Jiaoxiling tunnel collapse,this paper discussed the treatment method,construction progress and resource input.The finite element analysis software FLAC3D was used to simulate the advanced small pipe grouting scheme adopted in the process of landslide treatment,and the comparison and analysis were made with the actual monitoring data in the field.It was found the on-site monitoring values were larger than the simulation values,and the numerical results were within the normal deviation range,which further verified that the advanced small catheter grouting scheme is simple,fast,safe and economical.
