FRACTURE OF ROCK SPECIMEN AND DECREMENT OF BEARING CAPACITY IN UNIAXIAL COMPRESSION
岩石试样单轴压缩的破坏形式与承载能力的降低

There are shear fracture, tensile fracture and compression failure like unstablepole in rock specimen under uniaxial compression. But it is shear fracture that mainlycauses the decrement of rock specimen's bearing capacity.
