摘　　要：以钢筋混凝土屈服线理论为依据，得出了其相应的各种破坏机构的四边支承钢筋混凝土双向板的极限承载能力公式，讨论了钢筋切断或弯起点位置变化对极限载力的影响，从而得出了一些有益的结论。On the basis of yield line theory of RC slabs, this paper puts forth the ultimate bearing capacity formulas corresponding to various possible failure mechanisms of RC slabs with four sides supported.It also discusses the influence of the cut off or bent up position of reinforcement on the ultimate bearing capacity. Some useful conclusions are derived.
