模糊理论在配合比设计方案比选中的应用

针对所设计的三种灌入式母体OGFC—16沥青混合料方案,通过室内试验,对其高温稳定性、水稳定性、马歇尔稳定度等因素进行了定量分析;通过现场测试,对母体的可灌性进行了定性分析。依据以上结果及经验判断,对各因素进行了权重分配。运用模糊理论对三种方案的综合性能做出整体评价,最终比选出最优方案,为施工提供了理论指导,对控制工程质量具有重要意义。

Application of Fuzzy Theory in Selection of Mix Design Plans

In view of three kinds of filling type parent OGFC—16 asphalt mixture plans,this paper made a quantitative analysis on their high temperature stability,water stability,Marshall stability and other factors through laboratory testing,and conducted a qualitative analysis on maternal groutability by the site test.Based on the above results and experience judgment,it carried on the weight distribution to various factors.It used the fuzzy theory to make overall evaluation on the three schemes of integrated performance,and finally chose the best plan which provided the theoretical guidance for the best construction scheme and had the important meaning on controlling the engineering quality.
