摘　　要：针对地铁盾构隧道施工中遇到的溶洞、空穴等地质灾害,提出了当无法从地面进行注浆加固处理时,如何利用盾构机配置的超前钻探系统在洞内进行溶洞钻探及注浆加固。本文结合工程实例,介绍了洞内溶洞处理施工流程,同时对洞内溶洞钻探、注浆加固施工的注意事项提出建议。This article, in view of the geological risk like the carst cavern and cave etc. during metro shield construction, proposes the ways to conduct carst cave drilling, grouting reinforcement, and introduces the construction procedure for probe detecting of the cavern, meanwhile it also gives some suggestion for the matters need attention during the probe drilling.
