| Abstract: | The station site has a complex double geological structure with evident pull-apart deformation.Its deformation model is a creep-fracture one,with an obvious concentration of principal and shear stress at the posterior edge of the site and the bottom of the rock-soil mass as well as the deposit body pull-apart and loose within it.The site will be unstable in the extreme conditions of reservoir storage and seism. |

| Keywords: | stress concentration pull-apart and looseness creep-fracture extreme conditions |
