摘要
采用新老混凝土粘结补强技术 ,进行了 4块平面尺寸为 5 0 0 0mm× 95 0mm、龄期为 2 5年的足尺钢筋混凝土桥面板粘结新混凝土的粘结性能试验研究。在此基础上 ,对一建造在水闸建筑物顶部的装配式钢筋混凝土简支梁式板桥 ,进行了全桥面板的新老混凝土叠合整修加固处理。近 5年的实际运行表明 ,该新老混凝土叠合整修加固方法经济可行 。
The application of the bond between the new to old concrete to strengthen RC bridge deck is studied in the paper. An attempt is made to study the mechanism of using the new to old concrete. Four pieces of specimens aged 25 years with the sizes of 5000mm×950mm are tested in the lab. Based on the test results, a simply supported bridge with precasted RC bridge deck is made of the new to old concrete. The strengthened bridge has been running for five years. It is found that use the new to old concrete to strengthen is suitable.
