摘　　要：基于模糊数学和突变理论,依托衡枣高速公路某连续梁桥,构建了高速公路服役连续梁桥质量评价指标体系。通过对连续梁桥的质量评价,得出结构主要病害类型及位置,并提出了病害修复方法。结果表明:突变-模糊综合评价法对服役桥梁的评价结果符合工程的实际情况,修复后的桥梁通过有限元结构验算满足规范要求,可为服役桥梁质量评价及病害修复提供依据。Based on fuzzy mathematics and catastrophe theory,the quality evaluation index system of continuous girder existing bridges on Hengzao expressway is established.Through the quality evaluation of continuous beam bridge,the main types and positions of structural diseases are obtained,and the methods of disease repair are put forward.The results show that the results of the catastrophe fuzzy comprehensive evaluation method for the existing bridges are in line with the actual situation of the project,and the repaired bridges meet the requirements of the code through the finite element structural check,which can provide the basis for the quality evaluation and disease repair of the existing bridges.
