Abstract:: Based on the seepage characteristics of porous media and the nonlinear constitutive relationship of soil, the coupling effect of seepage field and stress field was studied. According to elasticity and seepage theory, the fluid-structure interaction mathematical model and finite element format were established. The large-scale finite element analysis software ABAQUS was used to establish a nonlinear coupling model of the earth-rock dam of Yanshan Reservoir, and the fluid-structure interaction analysis was analyzed, and the calculation results showed that the interaction between seepage and stress in the dam body could not be ignored, and considering the coupling commission would adversely affect the stability of the earth-rock dam.
