| Abstract: | The water filling pressurization value for the concrete scroll cases of Liuhong Hydropower Station is optimized at first herein. And then, with the chose value, non-linear analysis on the scroll cases and their peripheral reinforced concrete is done with the three-dimensional finite element method, in which their stress and deformation conditions are analyzed under the temperature load as well. Furthermore, a primary analysis on the vibration characteristics of scroll cases is given at last. |
