Overview

Field measurement reveals structural response impacts in underwater tunnel construction, suggesting considerations for engineering practices.

Key Points

  • This research examines the structural response of segmental lining during and after underwater tunnel construction.
  • Field measurements of a high-speed railway shield tunnel in China
  • Data collection from pre-installed sensors measuring concrete strains
  • Analysis of internal forces based on measured strains and construction process
  • Field dataset captures structural response characteristics from assembly to stable stage
  • Construction activities significantly influence internal forces of segmental lining
  • Grout layer impact on subgrade modulus is crucial for accurate estimation of bending moments
