摘要：PROBLEM TO BE SOLVED: To longitudinally provide a hole of an upper end opening on a cured rod-like body made from a cement bad cured material and to provide a method for evaluating a rod diameter by a peak frequency obtained by hitting inside the hole and a measuring instrument suitable for the execution of this你们可知道
method.SOLUTION: This method is a method for evaluating a rod diameter of a cured rod-like body C made from a cement bad cured material cast-in place in a vertical cave B, and includes: a step of drilling a boring hole B in the rod-like body; a step of inrting a hitting device 8 with an acceleration nsor into the boring hole; a step of hitting a predetermined place of an internal surface of the boring hole using the hitting device; a step of measuring a time history waveform of the cured bar-like body by the cement bad cured material of a hitting place; a step of obtaining a peak frequency of the vibration of the cured rod-like body by the cement bad cured material by subjecting the waveform to Fourier transformation: and a step of evaluating the rod-diameter of the h
itting place of the cured rod-like body by the cement bad cured material from this
