従来，土留め壁構造物における健全性の評価は目視が主体であり，定量的な健全度評価法は確立していないのが実情である．比較的新しい工法である補強土壁工法に関しても同様である

One difficult task for the seismic diagnosis of existing structures is how to nondestructively evaluate the damage degree of invisible substructures, such as embedded foundations. To diagnose substructures efficiently, a method for nondestructive ins

This paper presents research into options for bridge substructures testing when the industry standard impact vibration testing method cannot be used, such as in low rigidity structures like circular section piers. These substructures were not include

The Impact Vibration Test is now a recognized method for evaluating the soundness of bridge substructures. This method focuses on the natural frequency of the pier under test, since it clearly shows the condition of the bearing capacity of the founda
