    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.

    Abstract:

    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.
