The change of reservoir water level and temperature will affect the seepage pressure and deformation of the dam,which have a certain impact on dam stability.Taking the earth-rock dam project as an example,the effects of water level change and air temperature change on dam seepage and dam body temperature is considered.The heat conduction,convection and diffusion equations in the porous medium model were used to simulate the law of dam seepage and temperature gradient changes under the unstable boundary conditions of variable water level and temperature.The research results can provide reference for relevant earth-rock dam projects.
