摘　　要：修补后新旧混凝土能否很好地共同工作取决于新旧混凝土界面粘结性能。对于新旧混凝土粘结问题的根本解决需要从混凝土材料微观结构的角度阐明其粘结机理 ,建立微观结构的分析和宏观力学性能之间的联系。本文试图从理论上分析薄弱界面的成因 ,以寻求解决问题的途径 ,用于指导工程实践操作。? The bonding behavior of new to old concrete interface is the key factor to decide whether the new and concrete could work together satisfactorily.We deem the only way to solve this problem is to clarify the bonding mechanism in the view of micro structure of concrete material,and create the relation between micro structure analysis and macro mechanical behavior.In the present paper,we attempt to analyze the cause of formation of weak interface theoretically in order to seek ways of solving this problem and to instruct practical application. 〔
