The invention relates to a forming method for a precast concrete member bonding surface. The method comprises the following steps that a concrete member is precast; an air bubble film is attached, specifically, the air bubble film is mounted on the inner surface, corresponding to the bonding surface of the precast concrete member, of a template; and the air bubble film is peeled off, specifically,after the template is dismounted, the air bubble film is peeled off, and concave pits which are consistent with the air bubble film in size and arrangement rule are formed in the precast concrete member bonding surface. According to the technical scheme, through the forming method for the precast concrete member bonding surface, the roughness requirement for the precast concrete member bonding surface is met through the air bubble film, the construction process is simple and convenient, the surface quality is good, in addition, materials of the air bubble film are easy to take, the price is low, and the advantages of customization and easy demolding are achieved.
