The invention belongs to the field of rock mechanics and provides a device and method for preparing rock test pieces with different sizes and joint inclination angles. A device for preparing rock specimens of different sizes and joint inclination angles, comprising: a base, a rotating disk, and a fixing assembly for complete rock specimens to be cut. The complete rock specimen fixing assembly to be cut includes a T-shaped guide rail, a specimen end surface fixing assembly and a specimen side fixing assembly; the rotating disk and the base are hinged through a ball hinge; the T-shaped guide rail has an arc groove and is engraved with a scale, T The glyph-shaped guide rail is fixedly connected to the rotating disk; the fixed assembly on the end surface of the test piece is slidingly connected to the T-shaped guide rail; the fixed assembly on the side of the test piece is fixedly connected to the rotating disk through a fixed plate. The device and method of the present invention can meet the preparation of rock samples of different sizes and joint inclination angles by adjusting the device components, improve the preparation accuracy of the joint inclination angles of rock samples of different sizes, and have unique structure, reasonable structure, convenient operation and durability Etc.
Description
technical field [0001] The invention belongs to the field of rock mechanics, and in particular relates to a device and method for preparing rock test pieces with different sizes and joint inclination angles. Background technique [0002] There are a large number of jointed rock masses, and the preparation of jointed rock samples with different dip angles in the laboratory usually requires the following steps: drilling and coring, end cutting of complete rock samples, cutting of different joint dip angles of complete rock samples, bonding jointed rock samples and grinding . Such as figure 1 As shown, several common joint dip angles during the test are 0°, 15°, 30°, 45°, 60°, 75° and 90°. According to different test requirements, complete rock samples of different sizes need to be cut into For jointed rock samples with different joint inclination angles, for example, in jointed rock uniaxial and triaxial static mechanical tests, the length-to-diameter ratio of joint rock sam...
