Similar materials of surrounding rock are used to simulate the mass in geomechanical model test. The discrete element method has advantage simulating behavior fractures between particles at micro-scale, which can further reveal failure mechanism combination with However, microparameters need be calibrated before simulation. In this paper, three kinds bond models described, and their application is analyzed. soft-bond determined as constitutive particles' contacts. Then, simulation biaxial...
To determine the static and dynamic properties of similar materials for engineering rock mass, triaxial tests were conducted on mass materials. The comprised barite powder, quartz sand, gypsum water, laundry detergent, based an optimal design. relationship between deviator stress axial strain was investigated under various loading confining pressure. test results reveal that deformation characteristics gradually develop from brittleness to ductility with increase in applied pressure, elastic...
