对不同内径的环形大理岩试件进行静、动劈裂试验，研究不同加载速率下大理岩试件的抗拉强度和破坏模式随内半径与外半径之比（rho）的变化规律。结果表明，盘状岩石试件的动抗拉强度约为其静抗拉强度的5倍。环形试件的破坏模式与内孔尺寸和加载速率有关。静载试验中，当岩环内半径与外半径之比足够小时(rho
Static and dynamic splitting tests were conducted on ring marble specimens with different internal diameters to study the tensile strength and failure modes with the change of the ratio of internal radius to external radius (rho) under different loading rates. The results show that the dynamic tensile strength of disc rock specimen is approximately five times its static tensile strength. The failure modes of ring specimens are related to the dimension of the internal hole and loading rate. Under static loading tests, when the ratio of internal radius to external radius of the rock ring is small enough (rho
