摘要
宁波招宝山大桥加固方案中 ,原箱梁底板与腹板内侧新增 2个劲性钢筋混凝土小梁 ,为研究新旧混凝土共同受力情况 ,进行了模型试验。介绍了这一试验的分析结果。实验结果表明 ,新旧混凝土能很好地共同承受轴向压力 。
In Ningbo Zhaobaoshan bridge strengthening plan, two stiffened girder were add to the place where the formerly designed base plate and inner wall of web plate of box beam are conjuncted, A model test was done to study whether the new concrete participate in taking loads with the old. The result of the test was introduced, the result of the test demonstrated that the new concrete can participate in taking not only the axial compressive stress but the bending stress together with the old concrete.
