摘要
在高速公路沥青路面结构方案优选过程中,模糊隶属度函数主要用于确定功能要素重要性系数。介绍模糊隶属度函数的概念,确定沥青路面使用性能评价常用指标,应用模糊隶属度函数进行功能要素的排序,以及3种典型沥青路面结构的功能评价。结果表明,模糊隶属度函数可以有效提高高速公路沥青路面结构方案优选效果。
During optimal selection of plans for expressway asphalt pavement structures,the fuzzy membership function is mainly used to determine importance coefficients of functional elements.This paper introduces concept of the fuzzy membership function,determines common indices for evaluating the application performances of asphalt pavement,adopts the fuzzy membership function to sequence the functional elements,and assesses the functions of three typical asphalt pavement structures.The results show that the fuzzy membership function can effectively improve the effect of optimal selection of plans for expressway asphalt pavement structures.
