英文摘要

We tested basic physical characteristics of the outcrop samples with developed beddings from the Lower Silurian Longmaxi in Southeast Chongqing. Based on these tests, we carried out the research of shale mechanical characteristics under the different bedding angle conditions. Our tests indicate that the uniaxial compressive strength of shale increases linearly with the increase of the bedding angle of the samples. The extending direction of failure surface is consistent with the bedding angle when the angle is between 0°-45°. While the angel ranges from 60° to 90°, only a partial consistency between the crack distribution and angle of bedding was reached. Rock will produce the splitting failure because of the inconformity between the main failure surface extension and the angle of bedding. The tensile strength of samples range from 2.872 0 MPa to 10.490 0 MPa, and the stiffness 556.62-1 842.98 MPa, which shows wide dispersion. when the angle between core drilling direction and layers changes the mechanical properties of shale vary greatly., we should take into account the anisotropic of mechanical characteristics during the designs of drilling and fracturing of shale gas. ©, 2015, Academia Sinica.
