功效系数法在水泥稳定材料配合比设计中的应用

Application of Efficiency Coefficient Method in Design of Mixing Proportion for Cement Stabilized Material

水泥稳定材料的配合比设计方法主要考虑技术指标,对经济指标关注很少。对满足强度要求的多个配合比设计方案,将价格也作为考察指标之一,运用功效系数法加以评价和优化,获得性价比最佳的配合比设计方案,既能保证质量,又可节约工程成本,并总结出一种多指标权衡的配合比设计评价和优化方法。

The design of mixing proportion for cement stabilized material does not take the economic index into consideration, but the technical ones mainly： For many schemes of mixing proportion design satisfying strength requirement, the price shall also be considered as one of the study indexes. The efficiency coefficient method is used for evaluation and Optimization so as to obtain the mixing proportion design with best performance price ratio, which not only ensures the quality but also saves the engineering cost; moreover, a kind of evaluation and optimization method weighed by multiple indexes for mixing proportion design is summarized.
