摘　　要：为了准确预测材料组成和配合比等因素对混凝土自收缩率的影响,提出了一种基于层次分析与模糊评判(AHP-Fuzzy)的高性能混凝土自收缩评价模式,首先应用层次分析法建立自收缩评价体系并确定各指标权重,其次应用模糊综合评判理论对已有的高性能混凝土设计方案进行自收缩性能评价,并将所得的计算分值定义为自收缩度.实例验证,自收缩度越高,则实测试件自收缩率也就越大.In order to evaluate the influence of material constitutes and mix design on the autogenous shrinkage of high performance concrete, this paper brings forward a new method of autogenous shrinkage evaluation based on AHP-Fuzzy method. It contains two steps： First, utilizing the AHP theory, we set up the estimated system and fix the proportion in each target; Second, we calculate the score by using the Fuzzy comprehensive appraisal and the score is defined as the autogenous degree. By validating to the experimental result, we find that the more the score of autogenous degree is, the more the autogenous shrinkage ratio is. Therefore, this method has important significance for the diagnosis of concrete autogenous shrinkage.
