摘　　要：在桥梁运营期间,施工和设计质量缺陷、材料的老化等不利因素影响,会导致桥梁的结构损伤累积、抗力衰减和功能退化,从而影响桥梁使用的耐久性。将层次分析法与灰色理论应用到预应力混凝土桥梁的耐久性预测研究中,建立基于AHP-GM理论的预测模型。During the operation of the bridge,the construction and design quality defects,material aging and other adverse factors will inevitably lead to the accumulation of structural damage,resistance attenuation and functional degradation of the bridge,thus affecting the durability of the bridge.In this paper,analytic hierarchy process and grey theory are applied to the durability prediction of prestressed concrete bridges,and a prediction model based on AHP-GM theory is established.

关 键 词：预应力混凝土桥梁 耐久性 AHP-GM理论 预测模型
