An in-situ shear test device for holes in rock-soil mass include an axial loading system, a cutting power system, a rotation system, an upper cutterhead control system, a shear test system, and a lower cutterhead control system, which belongs to the field of geotechnical engineering and geological engineering technology. The device can accurately obtain the in-situ shear strength parameters in the hole of rock and soil, improve the engineering design level, and ensure the safety and stability of the project. The device adopts an in-situ shear test device in the hole of rock and soil mass with the above structure, which can solve the problems of difficulty in in-situ shear test for the holes in deep rock-soil mass, lack of test device, difficulty in radial test, difficulty in loading while shearing, and difficulty in multi-point in-situ test.
