| Abstract: | With the under-construction case of the section between Shuangjing and Jingsong of No. 10 Line of Beijing Metro, analysis was made on the construction technology for single tunnel-single line-step excavation method. According to the analysis, the degree of influence to surrounding rock stability by technology of undercutting with shallow overburden, inclucling pre-strengthening, excavation sequence and step length, can be very clear. |
