摘　　要：在内置胶囊自修复混凝土梁弯曲试验的基础上,通过对氰凝胶黏剂和聚氨酯胶黏剂两种不同梁二次开裂情况的分析,总结了自修复混凝土梁二次开裂的三种模式,并围绕梁的开裂荷载和二次开裂模型,分析了胶黏剂性能对自修复效果的影响.On the basis of bending experiments of self-repairing concrete beams with embedded capsules,the author gave an analysis of the two secondary cracking situation,including beams filled with TY-6638 polyester adhesive or cyanogen gel adhesive,then the three kinds of secondary cracking patterns to self-repairing concrete beams were summarized.Finally,the paper discussed the influence of adhesive properties on self-repairing effect,based on the cracking load and secondary cracking patterns of beams.

关 键 词：自修复混凝土 弯曲试验 修复胶囊 二次开裂模式
