AEセンサーを用いた打音検査によるグラウンドアンカーの緊張力評価 その1
概要
The purpose of this research is development of tension measurement method using hammering sound diagnosis technology using Acoustic Emission sensor. Experiments using actual size anchors and FEM analysis quantitatively evaluated the relationship between the vibration characteristics of the anchor head and the tension introduced into the anchor. As a result, it is possible to evaluate the anchor tension based on the natural vibration characteristics of the anchor head.
