通过三维有限单元法电算分析，讨论了滑雪道式溢洪道的应力分布，提出了这种结构的主要 正应力分布规律、温度应力和地震的影响。最后还提出了进一步提高三维有限单元法电算精度的 途径（应力修匀）。
The three-dimensional finite element method is used to calculate and analyze the stress distribution of the piste-type spillway. The main normal stress distribution law, the temperature stress and the earthquake influence of the structure are proposed. Finally, the ways to further improve the accuracy of three-dimensional finite element method (stress trimming) are also proposed.
