【 摘 要 】

In order to study the influence of uniaxial compression test conditions on the strength and deformation characteristics of single-fractured similar rock with different penetration degrees, the author conducted the uniaxial compression test on prefabricated single-fractured similar rock using TAW-200 electronic multifunctional material mechanics testing machine. And quantitatively analysed the relationship between strength, elastic modulus and stress-strain of single fracture similar rock under uniaxial compression. The results show that the influence of uniaxial compression test on the peak strength is related to the penetration degree. The peak strength of specimens is the largest when there is no damage and the smallest when there is complete penetration (100%), but the peak strength of specimens not only decreases with the increase of penetration degree, but also relates to the crack dip angle. When the crack dip angle is different, the variation law of peak strength with penetration degree is also inconsistent; The influence of uniaxial compression test on elastic modulus is also related to penetration degree and crack dip angle, but the influence degree is different.
