摘要：In this paper, the failure process of sprayed concrete under tension is numerically studied through the use RFPA3D (Three-Dimension Realistic Failure Process Analysis). The numerical test on the sprayed concrete under biaxial tensile stress is conducted, and then four specimens with different thickness of the sprayed concrete layer are analyzed and compared. The comparisons show that along with the increase of the thickness of the sprayed concrete layer, the load support capacities also increase with a decrease in flexibility. It is indicated that the thickness of the sprayed concrete layer is an important factor influencing the crack distribution and load support capacities of the specimens.
