OBSERVATION OF EARTHQUAKE RESPONSE OF SUBWAY TUNNELS

抄録（英）：
Observation of earthquake response of subway tunnels has been carried out by Teito Rapid Transit Authority since 1976. By some analyses using the accumulated records, the following facts are found. 1) The motion of the surrounding soil affects strongly the behavior of subway tunnels. The influence of dynamic characteristics of tunnels is small. 2) The difference between the acceleration of tunnels and that of ground surface varies according to geologies. 3) In shield tunnels, the tangential strain of the diagonally upper part (45 degrees from the crown) is larger than that of the side part, the axial strain of ring joints is larger than that of segments.
