Abstract

Disclosed are a testing system and method under fluid-solid coupling effects. A dynamic stress field during fluid flow, deformation of a porous rock framework, real-time evolution of the stress field and deformation of a fluid-solid interface under fluid-solid coupling effects can be obtained, on the basis of a collected photo-elastic stripe image and a surface deformation image. A stress field of a solid framework and fluid in porous rock, and a strain field of the solid framework and the fluid-solid interface under fluid-solid coupling effects can be visually and quantitatively displayed by means of a display device.
