Numerical simulation and optimization of mechanical properties of step surfaces for stepped spillway

Abstract

Abstract: With the help of ANSYS finite element analysis software, the stress state of step surface of stepped spillway dam under the action of water flow near the dam body has been concerned, and the attempt to optimize and improve the stepped spillway dam has been carried out, followed by the comprehensive comparison between the original model and optimization scheme. The calculation results show that the stress singularity is easy to appear in the corner of the step, which will endanger the safety of the structure. However, this situation can be improved by adopting the optimization and improvement measures of the fillet in the corner of the step without basically affecting the energy dissipation performance.

Key words: stepped spillway dam, fluid-structure coupling, mechanical properties, optimization scheme
