摘    要:根据国内35个民用机场427个实测水泥道面芯样的劈裂强度测试结果,分析了道面结构强度变异性的分布规律,并采用方差分析手段计算了道面结构强度与机场使用年限、飞行区等级、道面位置、不同机场等因素之间的显著性影响水平.分析表明民用机场水泥混凝土道面结构强度的变异性是客观存在的,采用基于结构强度变异水平等级的可靠度系数处理这一问题更为合理.为此,根据道面结构强度变异系数的累积分布频率推荐了其变异水平分级标准,并计算了相应的可靠度系数,可为我国民用机场水泥混凝土道面设计规范修编中引入可靠度方法提供参考.

关 键 词:机场道面  水泥混凝土  结构强度  分布规律  变异性  可靠度

Abstract:Based on the in situ data of 427 pavement cores including 35 civil airports, the structural strength variability was analyzed and the variability distribution pattern was provided. The results of the analysis of variance indicate that pavement service time, airfield grades, various locations, and respective airports accept the significance test mostly, so the pavement structural design based on reliability is more reasonable. In the end, the reliability coefficient in pavement design was proposed based on the structural strength variability accumulative frequency distribution.
Keywords:airport pavements  cement concrete  structural strength  distribution pattern  variability  reliability
