Abstract: To investigate the failure process of fault rock burst in tunnels, a large-scale physical model test is conducted. Using the 3D printing technology of the wet-material extrusion deposition molding process, a 2 m × 2 m × ...

Abstract: Shear failure is a typical failure mode of rock masses in underground engineering. Conducting shear tests of rocks in the laboratory is an effective research method. In this paper, a shear box is presented that can be used ...
