| 摘 要： | 国内某正在建设中的公铁两用大桥上层公路桥采用砼桥面系与桁梁结合梁，砼桥面板是预制的，而与钢桁梁结合处砼是现浇的．为了确定新、老砼结合面上的剪切强度和抗拉强度，完成了无钉、有钉共16个组合件的预制砼与现浇砼工地结合试验及结果分析．该成果已应用于该桥结合梁的后续研究．

| Abstract: | In order to determine the shear and pull strength on the combination surface of thenewly casted concrete and the precasted concrete for a certain bridge composite girders,theexperimnets on the combination of precast concrete and concrete casted on spot are carried,including 16 specimen. The results are analyzed and some conclusions are drawn. The resultslay foundation for the successive study of the bridge composite girders. |
