| 目的 对地坑过滤器滞留篮的过滤板进行刚度等效计算。方法 应用能量法和各向异性法对地坑过滤器滞留篮的过滤板进行等效刚度计算。结果 基于变形能相等的能量法得到的频率远大于地震反应谱的截止频率，该方法适用于滞留篮模型的工程要求。基于各向异性法得到的主频率与实际模型主频率相差14%，该方法同样适用于滞留篮的工程要求。结论 2种方法均可满足工程要求，各向异性方法更接近实际模型。最终采用基于能量法的模型和各项异性刚度等效过滤板都取得了较好的效果。 |

| The work aims to calculate the stiffness equivalent of the filter plate of the containment sump filter retention basket. Energy method and anisotropy method were used to calculate the equivalent stiffness of the filter plate of the containment sump filter retention basket. The frequency obtained by the energy method based on equal deformation energy was much larger than the cutoff frequency of seismic response spectrum, which was suitable for the engineering requirements of the stranded basket model. There was a 14% difference between the principal frequency obtained by anisotropy method and that of the actual model. Both methods can meet the engineering requirements, and the anisotropic method is closer to the actual model. Finally, the model based on the energy method and the anisotropic stiffness equivalent filter plates has good results. |
