摘　　要：供水工程通过合理采用开挖支护技术不仅可以提升小断面长隧洞施工质量,也能够为工程后期施工和运行奠定坚实的基础。对于供水工程施工项目而言,小断面长隧道开挖支护施工技术难度大,需要掌握科学的开挖方式,并落实好相关工作,这样才能够提高施工质量,保证工期,降低成本,提高工程运行效果,确保后续工程应用安全。基于此,笔者就小断面长隧道开挖支护施工技术展开研究,以引洮二期庄浪应急供水工程为例,对相关施工技术进行深入分析,掌握施工重难点,积极解决问题,保证工程质量。The reasonable use of excavation and support technology in water supply project can not only improve the construction quality of small cross-section long tunnel,but also lay a solid foundation for the later construction and operation of the project.For water supply engineering construction projects,it is difficult to excavate and support small-section long tunnels,so it is necessary to master scientific excava⁃tion methods and implement relevant work,so as to improve construction quality,ensure construction pe⁃riod,reduce costs,improve project operation effect and ensure the application safety of subsequent proj⁃ects.Based on this,the author studies the excavation and support construction technology of small section long tunnel.Taking Zhuanglang Emergency Water Supply Project in the second phase of Taohe River Diversion Project as an example,it makes an in-depth analysis of relevant construction technol⁃ogy,grasps the important and difficult points of construction,actively responds to problems and ensures the project quality.
