Case Structure

Based on the ANSYS program, a numerical model of spiral case structure of hydropower station is built. The nonlinear contact characteristics are introduced in this model. For the working conditions under the different internal water pressure, structural simulation analysis is conducted. The effect of the internal water pressure on the structure, and the mechanical characteristics and stress of reinforcement are analyzed. The evolution process of concrete cracks, from microscopic period to macroscopic period is exhibited. The reasonable scheme of optimization under internal water pressure is attained.
