Abstract Microbially Induced Calcite Precipitation(MICP) method has emerged as a new geotechnical technology that is widely applied for soil reinforcement. However，few researches on MICP applications in rock mass reinforcement had been reported. Herein，a single rock joint was chosen as an object，and artificial rock joint specimens were prepared by using rock-like materials and reinforced by MICP method and cement slurry，respectively. Laboratory direct shear tests were carried out on these specimens and the shear strength results were obtained. From the experimental results，it indicated that the peak shear strength of MICP reinforced artificial rock joint specimens increased with curing time，of which the increasing rate was rapid in early time，but became relatively slow in later stage. It was also found that the peak shear strength of MICP reinforced artificial rock joint specimens increased by as much as 15.3% by comparisons with that of unreinforced specimens. Furthermore，as a result of the cementation of CaCO3 layer between the upper and lower joint surfaces，the shear failure of MICP reinforced rock joints initiated from the shear failure of the interface between rock joint wall and CaCO3 layer and developed with increased normal and shear stress，then the final shear failure properties including the compression of CaCO3 layer and the shear off and crush of joint surface asperities were formed.

Key words： rock mechanics rock joint microbially induced carbonate precipitation(MICP) direct shear test shear strength
