The Tokyo Metropolitan Bureau of Waterworks has been carrying out seismic activity observations in a water supply tunnel in Misato City, Saitama Prefecture, since 1981_ This study examined the correlation between the ground motion and the generation of axial forces on the tunnel. As a result, the following was confirmed. 1) The ground motion is transmitted to the tunnel approximately as 1 to 1. 2) The stress in the lining shows a high responsiveness to the long-period component of the ground motion. 3) As for a medium earthquake, there is no great difference between the behavior of the segments constituting the primary shield tunnel lining and the second lining. Both are governed by the strain of the ground. Moreover, the simulation of an enormous earthquake based on observed earthquake waves, resulted ' axial force being much lower than the value in the initial design. キーワード（英）： - 記事区分： - 区分 　　　委員会論文集
