抄録（英）：
The simplified method for estimating the circumferential strain of a cavern from the particle velocity in rock during earthquakes was proposed. This method was based on the ratio between the circumferential strain of the cavern and the strain in rock obtained from the harmonic wave analysis by the boundary element method. From the comparison between the estimated strain calculated by this method and the strain observed at the Shin-Usami Tunnel along the JR's Ito line, the adequacy of this method was suggested. And the relation between the circumferential strain and the longitudinal strain observed at that tunnel was also clarified.
