STRUCTURAL DEFORMATION DETECTING DEVICE

摘要

A structural deformation detecting device comprises a vibration section (2) provided with a plurality of vibrators for vibrating a structure (4) serving as a measured object in a non-contact manner, a vibration measurement section (1) configured to detect the vibration wave (6) generated in the measured object (4) at any measurement position in a non-contact manner, a housing (3) on which the vibration section (2) and the vibration measurement section (1) are arranged at a specific interval (L 0 ), a time measurement section configured to measure the time elapsing till the vibration wave (6) in the measured object (4) is detected by the first vibration measurement section (1) at a specific position, and a deformation determination section configured to determine whether or not there is a deformation (5) by comparing the time taken for the transmission of vibration from the vibration position to the measurement position in a deformation-free state with the time measured by the time measurement section.
