摘要
基于熵权法,变异系数法,统计平均法,层次分析法等四种方法,采用2015年哈同高速公路沥青路面(佳木斯至集贤段)的实测数据对各评价指标的权重系数进行确定,计算出不同的PQI值,然后利用灰色关联度分析法对各影响因素进行评级,最后对比分析在进行路面评价和养护决策时,采用不同方法确定各指标权重系数会造成的影响。
There are many methods to ensure the weight coefficient, entropy weight method, variation coefficient method, statistical average method and analytic hierarchy process are picked in this paper. The measured data of Hatong highway from Jiamusi to Jixian part was selected to calculate the value of PQI . And use the method of grey relational analysis to rate each factor. Then the results were analyzed to investigate the influence of different computing method on PQI in pavement evaluation and maintenance decision process.
