预应力混凝土桥梁无损检测实验与缺陷识别研究

Key Points

• This research aims to improve defect identification in prestressed concrete bridges using nondestructive testing methods.
• Conducted experiments on a prestressed concrete continuous beam bridge served for 5 years.
• Implemented three mainstream nondestructive testing techniques and designed a data collection protocol.
• Developed and compared three defect identification methods and models.
• The hybrid model achieved an identification accuracy of 96.7%.
• Successfully identified multiple types of defects, enhancing bridge safety.
• Provides a reference for intelligent maintenance in bridge management.
