Compressive Strength, Triaxial-Compression Test, ABAQUS, Strain, Saturation, Fissured Rock Mass


The stability of the rock mass is generally constituted by the presence and the behavior of the discontinuities. The flow of water in a rock mass is one of the parameters that considerably affect fractured rock behavior, strength, and stability. This study proposes triaxial compression test to determine the stress, strain, and failure modes of the penetrating fractured rock mass under static load, and to reveal the relationship between its strength, deformation and strain rate, fracture slope, and fracture water. ABAQUS simulation proposes to identify material damage plasticity and generate stress and displacement of the specimen. Two kinds of the specimens which were plane and rough surface have been tested under drying state and saturated state conditions. The specimens were made with the slope of 30°, 45°, and 60°. Three-dimensional scanning is carried to illustrate the surface of the rock samples. Compressive strength of drying state specimens performed better than saturated state. The results also show that the greater slopes attained lower compressive strength and the rough surface attained higher compressive strength compared to plane surface. The simulation results attained similar trend with the experiment results.
