Abstract
As recent tendency, Cross section of shield tunnel becomes complicated, but stability in earthquake is not elucidated enough now. However, the design used seismic deformation method is general in business design. In this study, it is attempted to elucidate tunnel behavior by the centrifugal static shear box experiment which simulated seismic displacement method about circular tunnel, rectangular tunnel, and combination of these tunnels. As a result, it is confirmed that cross sectional power excels in 45 degrees direction of tunnel cross section. This paper is discussed about applicability of response displacement method by simulating experiment in elasto-plastic FEM analysis.
