Analysis of Stress and Deformation of Rockfill and Concrete Face for High Concrete Face Rockfill Dam
The deformation and contact behavior between concrete face and rockfill are important to the safety of concrete face rockfill dams. Based on the monitoring data of Shanxi concrete face rockfill dam, the stress of concrete face, deformation of rockfill and facing joints were studied. It is shown that...

Summary: | The deformation and contact behavior between concrete face and rockfill are important to the safety of concrete face rockfill dams. Based on the monitoring data of Shanxi concrete face rockfill dam, the stress of concrete face, deformation of rockfill and facing joints were studied. It is shown that the rockfill deforms under the water pressure and weight, and the concrete face is compressed in central and otherwise around abutment during the reservoir filling. As the upstream concrete face deforms as the result of the rockfill deformation, the peripheral joints appear tensile, shear and settlement deformation. In addition, the main deformation of peripheral joints is settlement, which has a significant relationship with water level, especially for the upper ones. |
