摘要
根据江龙大桥病害情况调查,计算分析,研究了刚架拱桥的受力特点,了解了刚架拱桥在目前超负荷运营情况下构件局部受力存在缺陷,导致该类型桥梁均存在相同病害,针对病害及受力特点提出相应的加固设计方法,供类似病害桥梁加固设计参考。
According to survey and analysis of disease in Jianglong bridge, the author studies the force characteristics of rigid-frame arch bridge, introduces the shortcomings in partial force of its members under the circumstance of overloading operation, shows that the same disease existed in the bridges with same type, and proposes relevant strengthening design methods in light of the disease and force characteristics, which to offer a reference for the bridges with similar disease.
