    • Alternate Title:
      Application of monitoring and measuring technology in soft rock tunnel construction.
    • Abstract:
      The soft rock tunnel often causes large deformation of the initial support, which affects the construction safety and progress due to the high pressure of surrounding rock. Taking the soft rock tunnel of Yunnan-Guangxi Railway as an example, we introduced the measurement method, data arrangement and application of monitoring and measurement, calculated the deformation of the initial lining of the tunnel through geotechnical business software FLAC3D. Combined with the analysis of monitoring data and the main causes of the deformation of the initial support, targeted construction measures were taken to control the deformation to ensure the construction safety of the soft rock tunnel. The deformation calculation, deformation monitoring and solutions can provide reference for other similar tunnel projects. [ABSTRACT FROM AUTHOR]
