半刚性基层材料抗裂性评价指标的灰色关联分析

Gray Correlation Analysis of Semi-rigid Base Material Anti-crack Evaluation Index

利用灰色理论对试验得到的多种干缩、温缩指标与最大干缩应变和最大温缩应变的相关分析表明:与半刚性基层材料的抗裂性关联度最高的干缩指标是干缩能抗裂系数,与半刚性基层材料的抗裂性关联度最高的温缩指标是温缩能抗裂系数。

Gray theory is adopted to analyze the relations between dry shrinkage index, tempera- ture shrinkage and maximal dry shrinkage strain, maximal temperature shrinkage strain. The results show that dry shrinkage index having the highest correlation with semi-rigid base material is dry shrinkage energy anti-crack coefficient, temperature index having the highest correlation with anti- crack is temperature shrinkage energy anti-crack.
