Abstract:	摘要： In this study, a series of centrifuge tests, modeling reverse fault rupture with 60° dip angle, were conducted in a dry sandy soil with a tunnel embedded in the soil layer. The test results showed that the tunnel and soil responses depended on the tunnel position, soil relative density and tunnel rigidity. Tunnels appeared be able to deviate the fault rupture path, while this deviation may be associated with significant rotation and displacement of the tunnel. However, a deeper tunnel was able to diffuse the shear deformation to a wider zone with an unsmooth surface displacement which may cause severe damage to the surface structures. Finally, the tunnel rotation, the location of the fault outcropping, the vertical displacement of the ground surface, the effect of tunnel rigidity on fault rupture path and surface displacement and the effect of soil relative density on fault–tunnel interaction were reported and discussed in this study. •The reverse faulting tests were conducted in sandy soil, with presence of tunnel.•With increasing the burial depth of tunnel, the larger shear zone develops.•As the density of soil become greater, the number of ruptures decreases.•The number of scraps at the surface is increased with presence of tunnel. 出版者： Elsevier Ltd 出版日期： 2014-10-01 出處： Soil dynamics and earthquake engineering (1984), 2014-10, Vol.65, p.151-164 資源來源： ScienceDirect (Journals) 版權： 2014 Elsevier Ltd 識別號： ISSN: 0267-7261 識別號： EISSN: 1879-341X 識別號： DOI: 10.1016/j.soildyn.2014.04.008
