公路隧道开挖及支护期间的施工质量控制

Construction Quality Control of Highway Tunnel During Excavation and Support

以实际的公路隧道开挖和支护施工过程为研究对象,分析和总结了适用于不同围岩等级的开挖和支护方案,并提出不同方案下的施工质量控制要点,为公路隧道工程的开挖和支护施工提供了一定的借鉴和参考。

This paper takes the actual highway tunnel excavation and support construction process as the research object,analyzes and summarizes the excavation and support schemes suitable for different surrounding rock grades,and puts forward the construction quality control points under different schemes,which provides certain reference for the excavation and support construction of highway tunnel engineering.
