The internal defects of rock mass have a significant effect on its mechanical properties and damage and fracture. The influence of fissure angles and bridge lengths on rock mechanical properties and failure was analyzed by uniaxial compression test and DIC technique. The research findings are as follows: The peak stress and elastic modulus of the samples have an obvious change trend with the change of the fissure angle. Compared with the length of the rock bridge, the fissure angle has a more significant effect on the mechanical properties of the rock. With the increase of fissure angle, the number of surface cracks, main failure cracks and surface spalling decreases, while the area of falling blocks increases obviously. However, with the increase of bridge length, the characteristics of crack propagation and spalling are basically the same. In the process of crack propagation, the connection of rock bridge is related to the fissure angle and the length of rock bridge. In the low fissure angle, the failure mode of rock samples is dominated by tensile failure cracks; With the increase of the fissure angle, the performance is as follows: the tension damage crack to shear damage crack transformation to form a mixed tensile shear damage mode; At the same time, with the increase of bridge length, the more difficult the rock bridge is to penetrate, and the local crack expansion failure changes from tensile-shear crack to tensile crack.

鉴于岩体内部缺陷对其力学性质和损伤断裂破坏有显著影响的问题,通过单轴压缩试验和DIC技术,分析了共面双裂隙类砂岩试样裂隙倾角和岩桥长度对岩石力学性质和破坏的影响。结果表明,随裂隙倾角变化,岩样峰值应力和弹性模量均有明显的变化趋势,相比于岩桥长度,裂隙倾角对岩石的力学性质影响更为显著;随裂隙倾角增加,岩样破坏时表面裂纹数量、主破坏裂纹和表面剥落数量均有减少,掉块面积却有明显增加,而随岩桥长度增加,裂纹扩展和剥落掉块特征基本相同;在裂纹扩展过程中,岩桥的贯通与裂隙倾角和岩桥长度均有关系;在低裂隙倾角时,岩样破坏模式以张拉破坏裂纹为主;随裂隙倾角增加,表现为由张拉破坏裂纹向剪切破坏裂纹转变形成了拉—剪混合破坏模式;同时,随岩桥长度增加,岩桥越难以贯通,裂纹扩展破坏则又由拉—剪混合裂纹向张拉裂纹转变。

鉴于岩体内部缺陷对其力学性质和损伤断裂破坏有显著影响的问题,通过单轴压缩试验和DIC技术,分析了共面双裂隙类砂岩试样裂隙倾角和岩桥长度对岩石力学性质和破坏的影响。结果表明,随裂隙倾角变化,岩样峰值应力和弹性模量均有明显的变化趋势,相比于岩桥长度,裂隙倾角对岩石的力学性质影响更为显著;随裂隙倾角增加,岩样破坏时表面裂纹数量、主破坏裂纹和表面剥落数量均有减少,掉块面积却有明显增加,而随岩桥长度增加,裂纹扩展和剥落掉块特征基本相同;在裂纹扩展过程中,岩桥的贯通与裂隙倾角和岩桥长度均有关系;在低裂隙倾角时,岩样破坏模式以张拉破坏裂纹为主;随裂隙倾角增加,表现为由张拉破坏裂纹向剪切破坏裂纹转变形成了拉—剪混合破坏模式;同时,随岩桥长度增加,岩桥越难以贯通,裂纹扩展破坏则又由拉—剪混合裂纹向张拉裂纹转变。

The internal defects of rock mass have a significant effect on its mechanical properties and damage and fracture. The influence of fissure angles and bridge lengths on rock mechanical properties and failure was analyzed by uniaxial compression test and DIC technique. The research findings are as follows: The peak stress and elastic modulus of the samples have an obvious change trend with the change of the fissure angle. Compared with the length of the rock bridge, the fissure angle has a more significant effect on the mechanical properties of the rock. With the increase of fissure angle, the number of surface cracks, main failure cracks and surface spalling decreases, while the area of falling blocks increases obviously. However, with the increase of bridge length, the characteristics of crack propagation and spalling are basically the same. In the process of crack propagation, the connection of rock bridge is related to the fissure angle and the length of rock bridge. In the low fissure angle, the failure mode of rock samples is dominated by tensile failure cracks; With the increase of the fissure angle, the performance is as follows: the tension damage crack to shear damage crack transformation to form a mixed tensile shear damage mode; At the same time, with the increase of bridge length, the more difficult the rock bridge is to penetrate, and the local crack expansion failure changes from tensile-shear crack to tensile crack.
