PROBLEM TO BE SOLVED: To provide a tension measuring device and a tension measuring method in which tension of a tendon in a fixed ground anchor can be measured at a low cost and with simple convenience.SOLUTION: In the vicinity of a peripheral edge part of a pressure receiving plate (1), a long fluctuation quantity display member (2, 2A) is arranged which indicates the fluctuation quantity of the pressure receiving plate (1) due to tension of a tendon (50). The entire fluctuation quantity display member (2, 2A) is formed in an L-shape, and a measuring device (7) is provided which measures a position of the end (22e, 22Ae) on the side isolated from the pressure receiving plate (1) of the fluctuation quantity display member (2). |
