摘要
在岩溶发育地区的隧道施工过程中,对隧道基底溶洞软基处理是隧道施工中的一个比较困难且十分重要的环节。文章以布孟2号隧道基底溶洞软基处治施工为例,阐述了隧道施工过程中遇到了基底溶洞软基地质的复杂情况,并结合软基特点,介绍了采用树根桩对隧道基底溶洞软基进行处治的设计方案、施工工艺和取得的效果,为类似隧道基底溶洞的软基处理方案设计和施工提供了借鉴。
During the tunnel construction in karst development area,the karst soft-foundation treatment of tunnel base is a difficult and very important link in the tunnel construction.With the karst soft-foun- dation treatment construction of Bumeng # 2 Tunnel base as the example,this article described the complex base karst soft-foundation geology situation during the tunnel construction, and combined with the characteristics of soft foundation, it introduced the design scheme, construction technology and achieved effect when using the tree root piles for karst soft-foundation treatment at tunnel base, which can provide the reference for the design and construction of soft foundation treatment scheme of similar tunnel base karst.
