Embodiment 1

[0039] The embodiments of the present application provide an automatic tracking system for mesoscopic measurements under the action of long-term rock creep, including a bottom support, a positioning support, a mesoscopic camera and a control system.

[0040] Wherein, the upper surface of the bottom support is a horizontal working surface; the bottom of the positioning support is arranged on the bottom support in a way that it can move along the working surface, and the height of the top of the positioning support can be adjusted. A microscopic optical camera used to collect microscopic images of the sample during the test is arranged on the top of the positioning support in a way that it can rotate in the horizontal plane, and the height of the top of the positioning support can be adjusted.

[0041] Specifically, the positioning support is arranged on the bottom support through a translational electric system. The translational electric system includes a first direction adjust...

Abstract

The invention discloses a mesoscopic measuring and automatic tracking system in long-term rock creep and a method thereof. The system comprises: a bottom support, the upper surface of which is a horizontal working surface; a positioning support, which is arranged on the bottom support, the bottom of which is movable along the working surface, and the height of the top end is adjustable; a mesoscopic optical camera for collecting mesoscopic images of samples during tests, which is arranged at the top end of the positioning support and is rotatable in a horizontal plane, and the height of the top end is adjustable; a control system, which is connected with the mesoscopic optical camera and controls the mesoscopic optical camera to acquire mesoscopic images of a sample at regular intervals.

Description

technical field [0001] The present disclosure generally relates to the technical field of experimental measuring instruments, and in particular to an automatic tracking system and method for mesoscopic measurements under long-term rock creep. Background technique [0002] A large number of infrastructure projects such as transportation, water conservancy and hydropower are constantly being built. During the construction of these projects, underground engineering often encounters the problem of large deformation of rocks. Under the long-term action of external loads, the stress, strain and failure form of rock mass with joints and cracks will change continuously, showing obvious creep characteristics. This creep characteristic of rock often leads to engineering instability and damage, which is harmful to engineering safety. pose a great threat. Especially as the depth of underground engineering continues to increase, the geological environment is more complex, high temperatu...
