浅谈隧道进洞施工方案

Constructing plan of tunnel stepping into hole

介绍了刷仰坡进洞施工方案,并从测量放样、两侧拱脚拉槽预留核心土、架立钢架反压回填、打设超前锚杆弧形导坑等方面探讨性地提出了不刷仰坡采用反压回填直接进洞的施工方案,为其进一步的研究提供了基础。

It introduces the constructing plan of up-slope stepping into hole, from measuring samples, side-arch preserving centralized soil, supporting steel pile back-fill and super anchor-pile arch hole, it discusses and brings forward the constructing plan of up-slope stepping into hole, gives foundation of further research.
