把加肋板分成板和肋梁两个部分，板作为Winkler地基上的板，用边界元方法分析；肋梁作为连续梁，用有限元方法分析，利用肋梁结点处力的平衡和位移的协调关系进行耦合求解。
The ribbed plate was divided into two parts: the plate and the ribbed beam. The plate was used as the plate on the Winkler foundation and analyzed by the boundary element method. The ribbed beam was used as the continuous beam and analyzed by the finite element method. The balance and displacement of the force at the node of the rib beam was used. Coordinated relations are solved by coupling.
