Description

technical field [0001] The invention relates to a formula and process for selecting materials for large-scale rock simulation structural surfaces in the field, which is suitable for collecting the surface morphology of rock structural surfaces in the field. Through this manufacturing process, structural surfaces can be simulated in various projects. The determination of engineering design parameters such as structural plane shear strength is of great significance. Background technique [0002] Rock mass is composed of rock blocks and structural planes. Field investigations have found that the instability and failure of engineering rock mass originates from structural planes, and the failure mechanism of engineering rock mass is largely controlled by structural planes. The shear strength of the structural plane of rock mass is a key parameter for evaluating the stability of engineering rock mass and formulating a reinforcement treatment plan. The direct shear test is the mos...
