Experimental research on debonding failure of concert structure with high strength steel wire mesh was conducted to investigate the failure characteristics of interface debonding between concrete and reinforcing layer. The effects of different polymer mortar reinforcing methods were discussed on Shear bearing capacity and shear strength of reinforcing layer, such as single side strengthening、plant bar strengthening and U-shaped strengthening. The results show that shear-bearing capacity can be effectively improved by means of increasing bonding area of reinforcing layer, such as U-shaped strengthening or extension length of reinforcement layer. Shear strength of reinforcing layer would be weaken at the same time. Shear strength and shear-bearing capacity of polymer mortar reinforcing layer would be substantially improved by means of planting shear reinforcement. According to the test results, the suggestion value of minimum ratio of planting bar was prevised for the reference of the application in actual application.
