：In view of the bond property of reinforced ultra-high performance concrete (UHPC) member, and by using the nonlinear spring element of ABAQUS, a simulation and analysis have been made of the bond-slip relationship of reinforced UHPC with different cover heights, bond lengths and rebar diameters, followed by a further inquiry into the influences on the bond properties. The results show that the ultimate interfacial bonding stress of reinforced UHPC increases positively with the increase of UHPC protective layer thickness, while decreases negatively with the increase of reinforcement diameter and bonding length. The thickness of the protective layer increases from a single steel bar diameter to 1.5~2.0 times the steel bar diameter, with the ultimate stress increasing by 17.3%~33.3%. When the diameter of reinforcement increases from 8 mm to 12 mm and 16 mm, the ultimate stress decreases by 16.5% and 28.8% respectively. Furthermore, with the bond length increasing from 4 times of the rebar diameter to 6~8 times the value, the ultimate interfacial bonding stress decreases by 14.7%~25.3% accordingly. The ultimate bond stress obtained by finite element analysis is in agreement with the computational calculation results, with a relatively lower error of about 2%.
