Abstract

The invention discloses a preparation device of random oriented multi-set joints rock bridge samples. The preparation device comprises I-shaped guide rails, a dead plate, L-shaped supports, angle control devices and insert devices. The lower part of the preparation device is composed of two parallelly-arranged pairs of I-shaped guide rails and rod pieces. A square formed by the I-shaped guide rails and the rod pieces has the same inner diameter as a sample box. The L-shaped supports are nested in the I-shaped guide rails. The angle control devices are fixed on the L-shaped supports. The insert devices are fixed on the angle control devices through fastening screws. Thus, all the above components together form a basic structure of the device. In comparison with the prior art, the invention has the following advantages: the device is practical and simple, and can manufacture multi-sets of joints; manufactured samples can be used in direct shear tests and true triaxial tests; and the device is convenient to use, has high precision and high practicability, and is adopted to achieve objectives of really stimulating joints, enhancing work efficiency, reducing experimental errors, optimizing test results and solving practical engineering problems.

Description

technical field [0001] The invention relates to a sample joint preparation device in civil and hydropower engineering tests, in particular to a sample preparation device and method for a rock bridge with multiple groups of joints in any orientation. Background technique [0002] In all kinds of engineering construction, including architectural engineering, structure engineering, underground engineering, municipal engineering, traffic engineering and water conservancy engineering, etc., it is necessary to consider the strength of engineering joint rock mass. Natural rock mass is usually in a certain stress state, divided by structural planes, with discontinuity and inhomogeneity, and easily penetrated by joints in any direction. The rock mass in actual engineering forms joints with different properties under various complex geological actions, which is of great significance to the study of the failure mechanism of rock mass under various stress states. Therefore, it is parti...
