| Abstract: | Monitoring measurement was an important part of New Austrian Tunneling Method (NATM). Based on the Meihuashan tunnel construction, some items of monitoring and measurement, such as vault settlement, surrounding rock convergence, etc. were designed to explore the surrounding rock displacement. According to the measuring data regression analyses and the stability state of surrounding rock, the most reasonable time of second supporting was decided. The results showed that safe construction of Meihuashan tunnel was improved under the new second supporting time criterion. |
