Experimental Study on the Mechanical Behavior of Yunnan Limestone in Natural and Saturated States

Figure 10

Failure modes of Yunnan limestone under different confining pressures. (a) Splitting failure. (b) Tension-shear mixed failure. (c) Single inclined surface shear failure. (d) Y-shaped shear failure. (e) X-shaped shear failure. The dashed line in red represents the tensile crack. The dashed line in green represents the shear crack.
