Shield tunneling is highly affected by the strata conditions and cutterhead design. As a result, the test platform can be used to study the rockcutter interaction. The dualmode TBM cutter experimental platform with low cost and multiple functions is developed on the basis of the existing singlemode experimental platform. The working parameters of the dualmode experimental platform are decided on the basis of the existing research results and the design experience of singlemode experimental platform. The functions, such as cutter pressing, linear cutting and rotary cutting, as well as the parameters variation, are achieved by designing the mechanical structure and hydraulic system. The static analysis of the frame structure is studied by means of ANSYS software; the strength and the stiffness of the designed platform are verified. In addition, the control system is designed.
