<P>PROBLEM TO BE SOLVED: To provide an axial force measurement method for a ground anchor that facilitates an axial force measurement with a simple device. <P>SOLUTION: In an axial force measurement method for a ground anchor 31 used for stabilization of a slope or the like, ultrasonic waves are oscillated at one lateral face of an anchorage 32 provided at the head of the ground anchor 31, and on the basis of an amplitude of ultrasonic waves transmitted to the other lateral face facing the one lateral face of the anchorage 32, an axial force of the ground anchor 31 is determined. <P>COPYRIGHT: (C)2013,JPO&INPIT |
