灰色聚类法在林区路面性能综合评价中的应用

         

摘要

A grey synthetic evaluation model based on center triangle whitening weight function, whose weights were calculated by the entropy method, was applied to the comprehensive evaluation of highway pavement performance in forest regions,in order to completely reflect the grey subordinate relationship between evaluation findings and evaluation factors, improve the confidence level of evaluation findings, as well as to make a proper and reasonable maintenance scheme. Five road sections in different forest regions in Heilongjiang Province were selected to reevaluate Pavement Quality Index (PQI) which is defined in the current specification of pavement performance. The maintenance types of those sections were determined. Compared with the original evaluation, the method involved in this paper achieved better evaluation effects.%为完全反映林区路面性能综合评价中评价结论与评价因素之间的灰色隶属关系,提高评价结论的置信度,以及正确合理地做出维修方案,使用基于中心点三角白化权函数的灰色综合评价模型,其权重由熵值法计算的方法确定,综合评价林区路面使用性能.共选取了5个黑龙江省林区道路路段,对现行规范中的路面使用性能指数重新评价.确定了5个路段的保修类型,并与原评价结果进行对比,取得了较好的评价效果.
