摘　　要：基于国内外学者关于既有桥梁状态评估方法的研究,建立既有节段预制桥梁结构损伤状态评估指标体系.提出基于层次分析法的既有节段预制桥梁状态评估方法,并在该方法的基础上,引入权重赋分法考虑各影响因素的重要程度对既有节段梁各结构进行权重赋分,给出了相应的桥梁状态评估公式,制定了节段预制桥梁状态评估标准.最后,结合一个既有节段预制桥梁损伤状态评估实例来演示本文所提出方法进行节段梁状态评估的实现过程.Based on the research of domestic and foreign scholars on the state evaluation method of existing bridges,the state evaluation index system of existing segmental precast bridge structure is established.The condition assessment standard of existing segmental precast bridge based on analytic hierarchy process method is proposed.According to the principle of analytic hierarchy process method,the weight assignment method is introduced to consider the importance of each factor to evaluate the damage condition of the existing damaged segmental beam,so as to form a new set of state evaluation methods for the existing segmental precast bridge.Finally,an example of damage condition assessment of an existing segmental precast bridge is used to demonstrate the implementation of the proposed method for segmental beam.
