To explore the failure mode and bearing capacity of the granite cladding panel under different reinforcements, flexural tests were conducted on the windward and leeward sides of 33 granite cladding panels with undercut bolt anchorage. The joints of the granite cladding panels were reinforced with metal ring, and the panel back was reinforced with glass fiber reinforced plastics (GFRP) in cross, diagonal, horizontal, and vertical paste; then the bearing capacity of the panels was analyzed.The results show that after the panel is reinforced at the joints, the failure mode of the leeward side is improved in the loading direction. Compared with the panel without joint reinforcement, its bearing capacity is increased by 0.50 times. The four GFRP reinforcement modes at the back of the panel can keep its integrity after failure emerges and also improve the bending capacity of the panel windward side in the loading direction by 2.30 times at most, verifying the feasibility of the reinforcement measure of granite cladding panels with undercut bolt anchorage for engineering applications.
