摘要： PROBLEM TO BE SOLVED: To provide an ultrasonic axial force measurement rock-bolt and a rock-bolt axial force measuring method which enables the easy and precise measurement of an axial force.
SOLUTION: The ultrasonic axial force measurement rock-bolt is of a steel pipe expansion type, and has an expandable steel pipe 20 and a measuring bar 50 for axial force measurement having benchmark points N1 to N5 for reflecting ultrasonic waves. Cutouts are formed as the benchmark points N1 to N5 on the measuring bar 50 on which each cutout is given a size approximately equal to that of the end face 52 of the measuring bar 50. The rock-bolt is provided with two or more of the measuring bars 50 having groups of the cutouts in such a way that a group of cutouts G1 on the measuring bar is shifted in a longitudinal position to the other group of cutouts G2 on the other measuring bar. The size of the cutout is determined using a cutout area ratio that is the ratio of the vertical wall area of the cutout to the total area of the section of the measuring bar perpendicular to its longitudinal direction.
