沥青路面未确知测度结构优选模型

高速公路投资额巨大，需要科学的路面结构选择方法。针对高速公路沥青路面结构方案评价过程中存在着许多不确定的知识和信息，应用未确知测度数学方法建立了高速公路沥青路面结构优选评价模型，该方法对评价空间实现了有序分割，通过建立多指标综合测度评价矩阵对不同方案进行识别排序。应用该模型对3种典型路面结构进行了综合评价。结果表明，采用该方法得到的评价结果能够较为客观地反映沥青路面结构的综合性能。

Optimal Selecting Model of Uncertainty Measurement for Asphalt Pavement Structure

Scientific method was necessary for road decision-maker to select high cost-effect ratio pavement structure scheme. According to the fact that many uncertain knowledge and information existed in the process of evaluating the expressway asphaltpavement structure schemes, an evaluation model of pavement structure schemes based on uncertainty measurement was put forward; This method implemented ordered division of assessment space, and could recognize and rank different schemes by comprehensive measurement matrix of multiple indexes, three typical design programs of expressway asphalt pavement structure were evaluated by that model. It is shown that the assessment can objectively reflect the comprehensive performance of asphalt pavement structure , which provides a new method and way for evaluation of pavement structure schemes.
