摘　　要：为实现阿联酋铁路二期D标段隧道安全、快速、高质量修建,开展成套设备机械化快速作业系统化研究。通过调研国内外已有资料,对隧道单作业面机械化施工人机资源进行科学合理的配备;基于掌子面力学平衡稳定性分析,研究得到S3级围岩采用全断面法开挖和S4、S6级围岩采用台阶法开挖可保证掌子面稳定性,满足规范要求;基于各级围岩适配的快速作业施工工法,通过建立数值软件计算模型,得到S3、S4、S6级围岩最大开挖进尺分别为4.5、2、1.5 m;总结阿联酋铁路隧道机械化施工工艺,对比分析机械化配套施工与传统方法施工的工序时间和施工工效。To achieve safe,fast,and high-qualified construction of the tunnel in section D of the second phase of the UAE railway,a systematic study on the mechanization and rapid operation of complete sets of equipment is conducted.By investigating the existing data in China and abroad,the man-machine resources for the mechanized construction of the single operation surface of the tunnel are scientifically and reasonably equipped.By using the method based on the mechanical balance stability analysis of the excavation surface,it is found that the grade S3 surrounding rock excavation with full-section method and grades S4 and S6 surrounding rocks excavation with bench method can ensure the stability of the excavation surface.Based on the rapid operation construction method adapted to surrounding rock at all grades,the numerical software calculation model is established.The maximum excavation footage of grades S3,S4,and S6 surrounding rocks is 4.5,2,and 1.5 m,respectively.The mechanized construction technology of railway tunnel in UAE is summarized, and the process time and construction efficiency of mechanized construction and traditional constructionare compared and analyzed.
