基于AHP-模糊数学的水泥路面压浆材料设计及性能研究

Study on Design and Performance of Cement Pavement Grouting Material Based on AHP-Fuzzy Mathematics

为了改善水泥混凝土路面板底脱空处治效果,采用层次分析法(AHP)和模糊数学理论,建立水泥路面压浆材料优选方案的多级模糊综合评价模型;选取粉煤灰及脱硫石膏以适当比例复合等量取代水泥,制得了水泥路面压浆材料,并利用建立的综合评价模型对水泥路面压浆材料的选择方案进行综合评价,得到了10种比较方案的优越度,最大优越度为71.61%,最小优越度为21.75%。为了验证模型的合理性,选取优越度为71.16%、70.92%、70.83%、21.75%所对应的方案进行了试验复演,结果表明该模型复演性好,可以较准确地反应压浆材料在处治板底脱空的成效,具有较好的工程实用价值。

In order to improve the treatment effect of void at the bottom of cement concrete pavement,the analytic hierarchy process(AHP)and the fuzzy mathematics theory are used to establish a multi-level fuzzy comprehensive evaluation model for the optimal scheme of cement pavement grouting material.The fly ash and desulfurized gypsum are selected to replace the cement in an appropriate proportion to prepare the cement pavement grouting material.And the established comprehensive evaluation model is used to comprehensively evaluate the selection schemes of cement pavement grouting materials.The superiorities of 10 compared schemes are obtained.The maximum superiority is 71.61%,and the minimum superiority is 21.75%.In order to verify the rationality of the model,the corresponding schemes with the superiorities of 71.16%,70.92%,70.83%and 21.75%are selected to repeat the experiments.The results show that the model has good repeatability,can accurately reflect the effect of grouting material in the treatment of slab bottom void,and has the good engineering application value.
