The mechanism of fractured sandstone in compaction creep process

In this paper, we construct the true contour of the broken rock for the first time. Moreover, we reproduce the two-dimensional accumulation pattern and realize the numerical simulation transformation of the compressive creep test of the broken rock. It is shown that the simulation results are in good agreement with the laboratory tests. The research shows that the smaller the particle size, or the higher the stress, the easier it is for creep breakage to occur.
