Influence Analysis of Dam Stress and Displacement Caused by Stiffness Degradation and Mass Loss

Abstract:

The concrete dam under dead load, water pressure load and wind load is in high stress state for a long time, whose safety is in a dangerous station to a certain extent. The static calculation of the dam was done by ANSYS. In order to know the static characteristics of the dam, and to provide a theoretical basis for dam health diagnosis and routine maintenance, the variation of the dam stress and displacement caused by the stiffness degradation and mass loss was studied. The influence degree of the dam mass loss and stiffness degradation on stress and displacement were discussed. The results show that stress along the dam height (Y direction) is higher than it along the horizontal direction (X direction), the maximum stress difference is to about 4 times. The influence degree of dam stress and displacement caused by stiffness degradation is more serious than those by mass loss.
