The project team has developed solutions for the protection and displacement control of subway tunnel shields and bridge structures. By employing research methods such as model tests, quantitative analysis, and engineering measurements,  the project team has established structural assessment models for subway shield tunnels and underground bridge structures. These models enable safety assessments of existing structures, evaluations of vibration and noise caused by railway traffic, and further exploration of safety protection and noise control standards for subway tunnels and underground bridge structures.

Potential Applications

The developed technologies  can be applied for real-world applications, including the assessment and repair of deteriorating subway shield tunnels, the protection of underground bridge structures affected by external construction activities, and the safeguarding of building structures impacted by rail transit vibrations. These efforts aim to enhance existing assessment and protection standards and measures.

Value Proposition

The project team focuses on revealing the mechanisms of bridge pile displacement, the causes of deformation and failure in shield tunnels, and the reinforcement mechanisms of new repair technologies through model tests, engineering measurements, and quantitative analysis. The research aims to lay an experimental and theoretical foundation for the safety assessment and analysis of subways, bridge piles, subway stations, and other road and bridge projects affected by adjacent projects and geological conditions. The project team also conducts large-scale pile soil box tests for shield tunnels and bridges to explore the interaction between underground geotechnical structures and soil. Alongside theoretical knowledge, the team has gained extensive engineering project experience, which lays a solid foundation for the successful completion of this project.
