| Abstract: | To evaluate reasonably the aseismic safety of active service concrete dams, an ageing
damage model is established by combining with attenuation function and the theory of linear
elasticity. And then it analyzes the dynamic response of concrete dam for a hydropower station. The
results show that the ageing degradation has significant impact on the dynamic damage of the dam
body; improvement of aseismic safety evaluation method of concrete dam lays foundation of further
study on the aseismic safety of concrete dam. |
