中文摘要
      针对目前机场水泥混凝土道面采用“部位→区域→单元”三层次分区计算道面状况指数(PCI)方法的复杂性,提出了机场水泥混凝土道面“部位→区域”两层次分区方法并分析了该方法的适用性.利用6个机场55个区域的实际病害信息,通过两层次分区方法计算区域PCI,并采用单因素方差分析方法计算道面区域所在部位、区域大小、不同机场等因素之间的显著性影响水平.结果表明,利用民用机场水泥混凝土道面两层次分区方法计算得到的区域PCI略小于规范中三层次分区方法的计算值,结果更偏安全;平均偏差仅为1.04,对区域的损坏等级评价基本无影响;部位划分、区域大小、不同机场对计算偏差无显著性影响.两层次分区方法可大大减少道面状况评价的工作量,可推广性强.
英文摘要
      Aiming at the complexity of the previous pavement condition index(PCI) calculation using triple-level partitioning method of part-area-unit, a novel double-level partitioning method of part area was proposed along with the analysis of its applicability. Area PCI was first calculated using double level partitioning based on the data from 55 areas in 6 airports. The significance of area location, area size and different airports was then analyzed using single factor variance analysis. The results show that the double-level partitioning method is safety preferable with an average deviation of 1.04 compared with previous triple-level one. The proposed method has little influence on damage level evaluation. Part identification, area size, and airports also have no significant influence on calculation deviation. The double-level partitioning method is recommendable and could significantly reduce workload for pavement condition evaluation.
