Abstract Due to the separate manufacturing of the upper and lower rock joints，the conventional molds have many defects，such as the large difference in performance between the upper and lower rock joints and the poor consistency in shear strengths. For the consistency of physical and mechanical properties between the upper and lower rock joints and the reliability of test result，a rapid and integrated manufacturing mold of rock joint has been developed by using the vertical surface plate for rock joint. The newly developed molds were mainly composed of the side plate，the bottom plate，the surface plate of rock joint，the screw rod，the nut and so on. It is not only simple in structure and convenient to be disassembled，but also low in cost and easy to be vibrated. The integrated and conventional molds were compared and analyzed regarding the smoothness of loading surface，surface porosity of rock joint，manufacturing period and result of direct shear test. The results show the integrated mold can realize the overall cast of upper and lower rock joints and ensure the consistency between the upper and lower rock joints. The rock joint panel placed vertically is found to beneficial to discharge the bubble and reduce the porosity by about 7%. The smoothness of the loading surface of sample is higer，which ensures the reliability and consistency of shear strengths of rock joint. Compared with the conventional mold，the integrated mold can shorten about 40% manufacturing period.

Key words： rock mechanics rock joint direct shear test manufacturing period
