摘要
结合太中银铁路离石隧道工程实例,从工法控制和现场管理出发,介绍了该隧道采用三台阶七步开挖法的施工总则和技术特点、施工方法、施工组织以及施工控制要点和注意事项等内容,总结了三台阶七步开挖法在软岩土质(Ⅳ、Ⅴ级围岩)隧道施工中取得的成功经验。
Taking Lishi tunnel project on Taiyuan-Yinchung railway for example, considering the construction control and on-site management, the paper introduces the general principles and technical features of tunnel construction, construction techniques, methods and organization, construction control, notices, et al., summarises the successful experience of the three-bench seven-step tunneling method in soft rock （rock grade Ⅳ,Ⅴ）.
