Abstract
By the collapse of ceiling panels in Sasago tunnel, it turn out completely inevitable the falling of the appendage by periodic inspection. In conventional inspection method, it can't fully grasp the soundness of the bolt for securing the appendage. While, with technology improvement of economical, high-performance sensors and handling of big data, it has been promoting the social device in the infrastructure field called "anywhere sensor". This paper focused on lumps in load tunnel, proposes a sensing method utilizing commercial sensors with MEMS technology and verifies its practicality. And proposes the tunnel conservation monitoring system with organizing the relationship with periodic inspection.
