Research on control measures for the impact of newly constructed structures crossing over existing tunnels at close range: a case study of the Beijing transportation hub project

Key Points

• The research identifies effective control measures for the impact of newly constructed structures on existing tunnels.
• Key evidence highlights that implementing these measures may reduce structural failure rates by up to 30%.
• The analysis focuses on construction practices and their impact assessment on tunnel integrity during the Beijing transportation hub project.
• This work supports the need for enhanced engineering guidelines to protect vital infrastructure, indicating a significant operational improvement.
