High earth rockfill dams are massive structures that play a crucial role in water resource management and flood control. At their heart lies a critical component known as the clayey core wall, which serves as an impermeable barrier against water seepage. Understanding the behavior of these core walls is essential for ensuring the safety and stability of these dams.

Soil-Water Coupling
Soil-water coupling analysis investigates the interaction between soil deformation and water flow. The weight of the overlying material and external loads can cause soil to deform, which in turn affects the flow of water through the pores. This analysis helps determine the pore water pressure and seepage characteristics within the core wall.
Soil-Thermal-Water Coupling
Soil-thermal-water coupling analysis extends soil-water coupling by considering the effects of temperature. Changes in temperature can induce thermal stresses and influence soil deformation and water flow. This analysis is particularly important in regions with significant temperature variations or where heat is generated within the dam.
Advanced Numerical Techniques for Multi Physics Coupling
State-of-the-art numerical techniques, such as the finite element method (FEM) and coupled Eulerian-Lagrangian (CEL) method, are employed to simulate multi physics coupling analysis. These techniques enable the accurate modeling of complex geometries and boundary conditions, providing detailed insights into the behavior of the clayey core wall.
