The Experimental Investigation on the Propagation Process of Crack for Brittle Rock Similar Material
Abstract A model experiment about brittle rock materials is performed in the paper. At first, the similar theory about model experiment is introduced, then the adoption of materials, experimental methodology and procedure are depicted, finally the experimental results and discussions about rock similar materials are obtained. The final conclusions are drawn that the cement content in the rock similar materials has great influence on the propagation of cracks and their mechanical characteristics. The brittleness, initiation stress, the maximum stress of rock similar materials increase gradually as cement content increases, and the vertical displacement, peak strain and connection stress decreases gradually. The existence of cracks reduces the peak strength of samples seriously. The great instructive significance in this experiment will be provided for future experimental investigation about rock similar materials.
