摘要
采用数理统计原理,运用SPSS软件对陕西省7条高速公路交-竣工平整度数据进行分析,得出了陕南、关中和陕北地区路面平整度衰变幅度均值分别为0.39m/km、0.28m/km和0.24m/km,这也将作为计算竣工验收推荐值的依据;再基于交-竣工平整度变化规律,建立了平整度竣工验收推荐值的计算公式:IRIju=IRIji+IRIs,可为今后平整度竣工验收标准提供有效的理论依据。
Using SPSS software for statistical analysis of the evenness data of 7 delivered-completed projects of asphalt pavement in Shaanxi Province, the average values of the evenness decay rate, which were from southern Shaanxi（0.39m/km）, the central Shaanxi plain（0.28m/km） and northern Shaanxi（0.24m/km）, were obtained. They will also serve as the basis of calculation of recommended value for the completion acceptance. Then based on the varying pattern of the evenness data of the delivered-completed projects, the recommended formula is established： IRIju=IRIji＋IRIs. It provides the effective theory basis for future standards.
