Considering all of above, combined the subsection of "the study of the repair and strengthening method for existing bridge" with the sustentation fund of Ministry of Education, the bond characteristic, failure mechanism and shear strength computation of interface between new and old concrete and their applications in bridge strengthening are studied through the model test with embedded bar or not. The research works are mainly concerned with the following aspects: Firstly, considering different influence factors, the full-range shear experiment of 6 groups with 18 Z-shape specimens is executed. The bond shear capacity of interface is studied as well as the degree of influence such as interface roughness, agent, strength of new and old concrete, the depth of embedded bar.
