Zusammenfassung:	The invention discloses a treatment method for improving the adhesive force of interfaces of new and old concrete. The treatment method includes the following steps that (1) shear reinforcement is reserved in an old concrete layer poured first; (2) chiselling treatment is carried out on an old concrete interface; (3) a high-performance interface adhesive is evenly applied on the old concrete interface to form an adhesive layer; and (4) after applying of the high-performance interface adhesive is completed, new concrete is poured immediately, the end of the shear reinforcement is anchored intoa new concrete layer, the new concrete layer is cured, and after the curing is completed, an adhesive structure of the interfaces of the new and old concrete is completed. According to the treatment method of the interfaces of the new and old concrete, the adhesive force of the interfaces of the new and old concrete is treated through a method of reserving the reinforcement in the old concrete, anchoring the reinforcement
