摘要
结合工程实例,通过对该大跨径连拱隧道施工过程中的工程事例分析,总结了施工方面的经验教训。对连拱隧道在软弱围岩大变形的特殊条件下的施工方法等方面进行了阐述,重点探讨了中隔墙施工的注意事项,旨在对以后同类型工程提供一些参考。
Based on the design examples of the large span muhi arch tunnel construction, the paper summarizes the experi- ences and lessons of such construction and introduces the construction method for the double-arch tunnel in special condi- tions of the large deformation soft surrounding rock with focus on the matters needing attention in the construction of the mid-partition wall, in order to provide some reference for similar engineering.
