摘　　要：目前,我国公路系统多采用规范所推荐的路面使用性能指数(PQI)来评价公路使用状况,实际上可能会掩盖了其中单一指标的重要影响。当某个指标评价较低,而另外3个指标评价较高时,也可能会导致整体PQI值偏高,因此不能客观反映公路的实际使用状况。为了使得评价路面使用状况的方法更具广泛性和易用性,通过引入灰色理论模型,结合规范推荐的评价指标,以现有采集到的反映路面状况指标数据,采用灰色理论模型的算法对这些数据进行整体的分析,从而对各个目标公路分别进行计分评价,根据得分高低,判断各目标公路的综合使用水平。研究结果表明:以上方法可以实现准确地评价路面使用状况。At present,the Pavement Quality Index(PQI)has been recommended to evaluate the road surface performance in China's highway system.However,it cannot objectively reflect the actual use of highways when the values of some variables are low while the others are high.In this study,in order to make the PQI method more comprehensive and easily available,the gray theory model was introduced to analyze the data as a whole,combined with the PQI evaluating system.Thus,the level of comprehensive use of the target road could be determined according to the score recorded by the evaluation system.The results showed that the method could accurately evaluate the road surface performance.
