摘　　要：为探索适合采用悬臂式掘进机进行水利水电工程隧洞施工的相应条件,达到施工优质高效、安全可控和节约成本,笔者以银屯—凡平隧洞施工为例,选取钻爆法和悬臂式掘进机开挖法从安全、质量、进度、成本等方面进行对比分析,得到两种施工方法在不同大小的隧洞断面和不同地质条件下应用的优缺点,从而确定采用悬臂式掘进机开挖法的合理使用范围,为后续类似条件的隧洞施工提供可参考和借鉴的经验。In order to explore the corresponding conditions suitable for the tunnel construction of water conservancy and hydropower projects by using boom roadheader,and to achieve high quality,high efficiency,safe and controllable construction and cost saving,the author takes the construction of the Yintun—Fanping tunnel as an example,selects the drilling and blasting method and the boom roadheader excavation method for comparative analysis in terms of safety,quality,progress,cost,and other aspects,the advantages and disadvantages of the two construction methods applied under different size tunnel sections and different geological conditions are obtained,so as to determine the reasonable use range of the boom roadheader excavation method,and provide reference and reference experience for the subsequent tunnel construction under similar conditions.
