Embodiment Construction

[0042] The present invention will be further described in detail below in conjunction with specific embodiments and drawings, which are explanations of the present invention rather than limitations.

[0043] The rock-soil compression-shear rheological testing machine provided by the present invention can be modified on the basis of the original old-fashioned rock block press, adding a horizontal shearing system, setting the test method, controlling the test process, and reading through the computer and the servo hydraulic system. The test results are obtained, but its development cost is relatively low, and it can be modified in the later stage according to different test requirements. Saving, stability, precision and easy operation are the main features of the present invention.

[0044] see Figure 1 to Figure 5 , a rock-soil compression-shear rheological testing machine, including a main frame, a vertical loading system and a horizontal loading system are arranged on the ma...

Abstract

The invention discloses a rock-soil pressure shear rheological testing machine and a testing method, the testing machine comprises a mainframe, a vertical loading system and a horizontal loading system are provided on the mainframe, and a servo oil pressure system controlled by a computer provides oil pressure to the vertical loading system and the horizontal loading system. According to the invention, a shearing apparatus, the horizontal loading system, a servo hydraulic system and an electric control system are added for realizing automation, control and accuracy of the tests. An original waste and old press mainframe and a vertical oil cylinder are used by the testing machine, thereby about 50% of cost can be saved, the testing machine aims at test materials such as rock, rock mass and soil / stone compound body, and can perform with the following tests: a compression test, a shearing test, a residual strength shearing test, a compression rheological and shearing rheological test.

Description

technical field [0001] The invention belongs to the technical field of rock-soil test equipment, and relates to a rock-soil compression-shear rheology test machine and a test method. Background technique [0002] The large-scale rock-soil compression-shear rheological testing machine is a kind of indoor test equipment used in the field of geotechnical engineering. The compression and shear rheological characteristics of rock and soil mass under the action of long-term force, so as to obtain the development and change law of stress and strain of engineering rock and soil mass with time, as well as quantify the mechanical index of rock and soil mass, providing scientific research and production Basic information. [0003] At present, many scientific research institutes in China are facing the replacement of the first batch of rock and soil test equipment. The test equipment is gradually transitioning from manual control to computer servo control, and the price of new equipmen...
