摘要
从横观各向同性理论出发,对现场采集的岩样进行室内单轴压缩试验和巴西劈裂试验,对岩石的各向异性参数进行了研究,探讨了弹性模量、抗压强度和抗拉强度随岩层倾角变化的规律,以及压力和拉力作用下各个不同倾角的岩样的破坏情况,并得出了横观各向同性岩体的弹性特征参数,为岩石各向异性的研究提供了一些有价值的参考信息。
Based on the theory of transverse isotropy, the uniaxial compression laboratory tests and the Brazilian tests for rock samples from field are carried out. The anisotropy parameters of rock is studeid, the elastic modulus, compressive strength and tensile strength changed with the change of the dip angle of rock stratum are discussed, and the failure conditions of rock sam- ple is also discussed, finally the index of elasticity characteristics of transverse isotropy of rock is determined, as valuable refer- ence for the research of anisotropy of rock.
