—vŽ| In order to grasp the interface behavior between concrete and resin repairing material with low elastic modulus and its generation and development process of internal cracks, the bending load bearing behavior of repaired concrete member by resin repairing materials with different thickness was studied and experimented. Moreover, the position orientation and formation mode of AE generation source corresponding to the cracks was conducted through the AE (Acoustic Emission) method. The results showed that the different repaired concrete members all can effectively ensure the interface integration, the detailed adhesion interface failure mechanism was defined. In addition, the importance of primer in interface integration was determined through comparative analysis.@
