Abstract: | Based on the line 7 of Shenzhen metro project,it focuses on the safety control technology for the construction one subway tunnel beneath existing subway station in short distance.Using numerical calculation to analyze and simulate the actual engineering situation.According to the engineering geological conditions,by comparing the results of the monitoring data analysis,this paper proposed the time-space effects of the full-sectional grouting.Much attention should be paid to the uplift of grouting reinforcing area.Adjusting the construction process timely can ensure construction safety in the process of grouting. |
