PROBLEM TO BE SOLVED: To perform a precise examination by setting a plurality of AE sensors around a structure supported by piles driven into the ground, inputting an AE signal generated in a breakage position to a processing device to calculate the breakage position and the degree of breakage. SOLUTION: A structure 10 is supported by concrete piles 20 driven into the ground, and a plurality of AE sensors 102 are set on the ground surface around the structure 10. After a large earthquake, an AE signal is generated from the breakage position of the pile 20, and this AE signal is detected by the sensor 102. The AE signal detected by the sensor 102 is inputted to a processing device to calculate the breakage position of the pile and the degree of breakage. |
