To provide a measuring method that can separately calculate displacement of a structure caused by each of a plurality of movable bodies moving in a row.SOLUTION: A measuring method includes the steps of: acquiring first observation point information including the time at which parts of an m-th movable body pass through a first observation point and physical quantities that are responses to actions; acquiring second observation point information including the time at which the parts pass through a second observation point and physical quantities that are responses to actions; calculating deflection waveforms of the structure caused by the parts; adding the deflection waveforms to calculate an m-th movable body deflection waveform; calculating a displacement waveform at a third observation point; and taking a waveform obtained by multiplying an m-th amplitude coefficient by the m-th movable body deflection waveform as an m-th amplitude adjustment deflection waveform, and calculating first to M-th amplitude coefficients such that the sum of the first to M-th amplitude adjustment deflection waveforms and the displacement waveform are approximate to each other.SELECTED DRAWING: Figure 24
