摘　　要：机场道面在飞机荷载与外界环境侵扰的综合影响下,其服役性能会逐渐衰减,进而引起结构风险上升,影响飞机的地面运行安全与飞行效率。国内机场以刚性道面为主,为评估机场刚性道面结构风险,采用层次分析法,确定了地基沉降、地基反应模量、PCN(Pavement Classification Number)与板底脱空4个关键指标的权重,提出了结构风险综合评价指标RPRI,给出了风险指标缺项工况下RPRI的计算方法,确定了结构风险的评价阈值,并进一步以上海浦东国际机场与天府国际机场为案例,展示了机场刚性道面结构风险评价方法。The operational performance of airport pavement deteriorates gradually under combined impacts of aircraft loads and environmental factors,leading to increasing structural risk and compromising the safety and efficiency of aircraft ground operations.Rigid pavements are predominant in China.To assess the structural risk of airport rigid pavements,the Analytic Hierarchy Process(AHP)was employed to determine the weights of key indicators,including foundation settlement,foundation reaction modulus,PCN(Pavement Classification Number)and void beneath slab.The study proposed RPRI,a comprehensive evaluation index of structural risk,developed a calculation method,and determined the threshold value of structural risk evaluation.Finally,the methodology for assessing structural risk in rigid airport pavements was illustrated taking Shanghai Pudong International Airport and Chengdu Tianfu International Airport as examples.
