Abstract: The upstream filling area of upper reservoir rockfill dam of Xiamen pumped storage power station makes use of weak weathering materials excavated from reservoir basin, while the downstream filling area uses fully weathered material excavated from reservoir basin. There are some differences with the compression modulus of upstream and downstream filling area due to different materials. Key technologies such as adjusting the interface angle of filling area and setting transition zone are proposed. As well, three dimensional finite element stress and strain analysis is performed, whose result shows that the deformation coordination and stability of the dam can be guaranteed.
