几种统计法在精确计算沥青路面松铺系数中的综合应用

摘要

Based on the analysis of factors which affect the calculation precision of loose paving coefficient of asphalt pavement, and combination with the test data of a highway asphalt bottom layer section , the Classical Statistical approach, Robust Statistical approach, T-test approach and Grubbs test approach were comprehensive used to calculate representative value and discrete coefficients, and remove abnormal values of loose paving coefficient . Analysis on the calculation results, the basic combination principles of several statistical approach were proposed at different situations, and offered an new ideas for similar data process and accurate calculation of indicator values.%在分析了影响沥青路面松铺系数计算精度因素基础上,结合某高速公路沥青下面层试验段检测数据,综合利用经典统计法、稳健统计法与t检验法、Grubbs检验法,对松铺系数异常值进行剔除并计算代表值和离散系数.通过对计算结果分析,提出了不同情况下各种统计法综合应用的基本原则,为同类型的数据处理和指标值的精确计算提供了新的思路和方法.
