摘　　要：根据全灌孔砌体和部分灌孔砌体在加载全过程中表现出的相同和不同,发现影响两类灌孔砌体出现差异的原因是砌块外壁稳定性的不同.依据适用于全灌孔砌体的砌块软化理论,在原模型中考虑稳定性的变化,将砌块软化理论的应用范围拓展至部分灌孔砌体中,提出用于分析部分灌孔砌体的修正模型.计算结果表明,提出的修正公式能够较为准确地预测部分灌孔砌体的抗压强度;与未修正公式的计算结果相比,修正公式的计算结果精度有较为显著的提升.Based on the fully grouted masonry’s block softening theory,a modified model for partially grouted masonry is proposed.According to the similarities and differences between the fully and partially grouted masonry,it is shown that the stability of the shell affect the performance of the partially grouted masonry.By considering the shell stability,the application scope of the block softening theory can expend to the partially grouted masonry.The calculation results show that the modified model proposed in this paper can predict the compressive strength of partially grouted masonry more accurately than the calculation results of the original formula.
