Method of measuring bending deformation amount and bending deformation amount measuring device

摘要

PROBLEM TO BE SOLVED: To provide a bending deformation amount measurement method capable of accurately measuring a multidirectional bending deformation amount of a measurement object, and to provide a bending deformation amount measurement device having a simple configuration used in the bending deformation amount measurement method.SOLUTION: In the bending deformation amount measurement method, two reference points P1 and P1 and one comparison point P2 are previously set at separate positions on the same straight line LB of a pile 2. After deformation of the pile 2, physical quantity correlating with a perpendicular separation distance of at least two directions between the linear line passing the reference points P1 and P1 and the comparison point P2 is measured, thereby measuring the multidirectional bending deformation amount of the pile 2. A bending deformation amount measurement device used for the measurement method is also provided.
