摘要
针对沥青路面使用性能综合评价复杂性、模糊性及缺乏合理评价方法等问题,采用主成分分析法,选取现行规范确定的沥青路面使用性能评价指标,借助Matlab数学工具对沥青路面使用性能进行综合评价;并与已有文献中利用灰色聚类决策评价方法所得结果进行比较。分析表明:主成分分析法用于评价沥青路面使用性能是可行的,而且能客观地反映评价指标对综合评价值影响的强弱,具有特有的优越性。
Due to the complex,fuzzy and unreasonable evaluation methods of synthetical performance evaluation of asphalt pavement,the Principal Component Analysis（PCA） and Matlab Software were applied and several main evaluation indexes determined by current specifications were employed to evaluate the performance of asphalt pavement.Compared with the results based on gray-clustering decision method,it could be indicated that the PCA was feasible and effective,which could reflect the effect of indexes on synthetical evaluation objectively and show special advantages.
