摘　　要：本文以引汉济渭工程5号隧洞为工程研究背景,结合施工过程中发生的连续塌方事故,在细致分析地质概况、施工工艺、塌方基本情况及产生原因的基础上,针对性提出"土模法"处置方案,并总结其施工应对措施及特点。该工法与常规塌方处理措施不同之处在于反向快速回填、修饰塌方体形成土模,因地制宜地利用塌方后现有形态的临时稳定资源快速施工支护体系,同时为施工人员提供安全作业空间。该种工法适用范围广、经济合理,能够快速有效地通过塌方段。Based on the research background of the No.5 tunnel in Hanjiang to Weihe River Project,and combined with the continuous collapse accidents occurred in the construction process,the relevant disposal plan of"soil model method"is put forward,and the construction countermeasures and characteristics are summarized on the basis of detailed analysis of geological survey,construction technology,basic situation and causes of collapse.The difference between the construction method and the conventional collapse treatment measures lies in the reverse rapid backfilling and modifying the landslide to form the soil mold,and using the temporary stable resources in existing forms after the collapse to quickly construct the support system,and providing safe working space for construction personnel.The method is widely applicable,economical and reasonable,and can pass through the collapse section quickly and effectively.
