With the continuous acceleration of urbanization, urban rail transit underground section projects have put forward higher requirements for supervision work due to their complex construction environment, high safety risks, and difficult quality control. With its advantages of flexibility, unique perspective, and efficient data collection, drone technology is gradually becoming an important tool for supervision units to improve supervision efficiency. This paper systematically analyzes the application value of drone technology in the construction supervision of urban rail transit underground section projects, and focuses on discussing its specific application scenarios in safety management and project quality control. Research has shown that the introduction of drone technology can effectively make up for the blind spots of traditional manual supervision, achieve objective retention and intelligent analysis of supervision data, significantly improve the accuracy, timeliness and safety of supervision work, and provide high quality for urban rail transit projects. Provide strong support for quality construction.
