Abstract
The earth-rock dams in Southeast Asia will be in long-term rainfall during the rainy season, and long-term rainfall infiltration will affect the seepage field of earth-rock dams. In this paper, COMSOL software is used to analyze the seepage field of earth-rock dam. Based on the basic differential equations such as Darcy's law and Rechards' equation built in software, the numerical simulation of seepage analysis is carried out. On the other hand, taking the stable seepage field as the initial condition and considering the rainfall conditions, further analysis and research on the unsteady seepage field will yield better results.
