| 摘 要： | 针对钢筋混凝土桥墩压弯承载力的计算，提出了基于极限状态的截面应力-应变关系，并分别以等效矩形应力图和混凝土应力-应变公式处理受压区混凝土的抗力计算图式，将轴压-压弯-纯弯的计算方法统一起来，使计算更简捷，最后给出工程应用实例．

| Abstract: | A unified calculation method is derived to evaluate the axial and bending bearing capacity of RC (reinforced concrete) piers. In derivation, the equivalent rectangular-stress graph and the stress-strain formula are respectively adopted, corresponding to the stress-strain relation for limited state. The method presented in this paper is applicable for calculating the bearing capacity of axial compression, compression-bending, and pure bending as well. An engineering example is given at the end of the paper. |
