摘　　要：针对山西省内21座不同类型桥梁的评估需求,论文提出了外观调查法和荷载模型检测法的桥梁承载能力评定方法。以刘虎狮特大桥为例,对桥梁各部件的损害程度进行量化评分,并建立有限元模型,结合现场检测数据计算桥梁的承载力。结果表明,刘虎狮特大桥检测点5、检测点7、检测点8、检测点9的承载能力评分小于80分,该桥综合承载能力评定为“良”。According to the evaluation requirements of 21 different types of bridges in Shanxi Province,the evaluation methods of bridge bearing capacity based on appearance survey method and load model detection method are proposed.Taking Liuhushi Super Large Bridge as an example,the damage degree of each component of the bridge is quantitatively scored,and the bearing capacity of the bridge is calculated by establishing a finite element model and combining with the field test data.The research results show that the comprehensive bearing capacity of Liuhushi Super Large Bridge is evaluated as“good”with the score of less than 80 points for inspection point 5,inspection point 7,inspection point 8 and inspection point 9.
