| Abstract: | In order to minimize the influence of metro shield tunnel perpendicularly crossing underneath existing tunnel on running municipal tunnel, a series of technologies, i.e. ground consolidation, floor reinforcement strengthening, monitoring data analysis, shield boring parameters and grouting parameters adjustment and ground conditioning, are adopted. The safety of the municipal tunnel and the metro shield tunnel and the construction quality of the metro shield tunnel have been guaranteed. |
