| Abstract: | As the existence of concrete cracks in constructed dams, there would be latent risk for these concrete hydraulic structures. In the paper, Dongzhou concrete pier was researched, mechanics method was used to analysis the pier safety in the three dimensional nonlinear finite element method. From the calculating result, some conclusions were gained about pier safety and the crack development in the future was forecasted. |
