摘要
提出在拱桥加固过程中施加配重调节拱圈内力的方法,阐述了配重法的理论依据,结合两座拱桥加固改造的工程实践,说明其具体的实施方法,并通过数值计算结果验证了配重法所取得的效果,可为同类拱桥的加固改造提供有益的参考。
Weight-matching method could be used in strengthening of damaged arch bridges to regulate the internal forces in the arch.Its theory foundation is expatiated in the paper.Also the engineering measures are discussed with two examples of damaged arch bridges.Furthermore,the effectiveness of the method is validated by computation,which could be a successful practice for repair and strengthening of the similar bridges.
