摘　　要：以玻璃管作为自修复混凝土的修复容器,从微分单元体受力平衡的角度选择适宜的玻璃管壁厚,通过试验测定不预埋玻璃管及预埋不同数量玻璃管后的混凝土试块抗折强度值,以抗折强度损失率定量估算玻璃管对混凝土基体强度的影响,并用于指导选择适宜的预埋管数量。试验结果表明,通过力学平衡建模估算可指导预埋玻璃管壁厚的选择;以抗折强度损失率定量估算玻璃管对混凝土基体强度的影响,可指导选择出适宜的预埋管数量。Glass tube being a repairing container of self-healing concrete, we can choose appropriate thickness of glass pipe wall from the perspective of differential unit force balance, and do exploratory testing research from the embedded pipe quantity＇s influence on the flexural strength of concrete matrix. Test shows that it can be used to guide tube size selection through mechanical equilibrium modeling to estimate wall thickness; loss ratio of embedded pipe effect on flexural strength of concrete matrix can objectively guide the number selection of glass tube.
