Embodiment Construction

[0023] The technical solutions of the present invention will be clearly and completely described below in conjunction with the accompanying drawings of the present invention. Apparently, the described embodiments are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.

[0024] Such as figure 1 , 2 As shown, when the pressure plate 10 in one embodiment of the present invention is applied to the triaxial testing machine 20, it is assembled between the stress (σ2, σ3) actuator 21 and the sample 30 on both sides of the triaxial testing machine 20 During the stress detection of the sample 30, the actuator 21 exerts lateral stress on the sample 30 through the pressure plate 10. The side of the pressure plate 10 that is in contact with the actuator 21 is the p...

Abstract

The invention provides a pressurizing plate. The pressurizing plate comprises a pressurizing surface and a pressure applying surface, wherein a plurality of pressurizing beams are arranged between the pressurizing surface and the pressure applying surface, so that the force transmitting direction of the pressurizing beams is consistent with the pressurizing direction of the pressurizing surface; flexible packing is fixedly connected between the adjacent pressurizing beams, so that the problem of low precision in a triaxial testing process in the prior art is solved. Thus, when a sample is axially deformed, a pressurized plate can be deformed axially as the axial deformation of the sample without affecting the applied force to a sensor. The precision and reliability of measured data are improved.

Description

technical field [0001] The invention relates to the technical fields of geotechnical engineering, building materials, and geological disaster research and application, especially a pressure plate. Background technique [0002] With the advancement of the modern economic process, the improvement of infrastructure and the application of new materials. The performance test of soil rock and geological rock mass has been widely used in geotechnical engineering, building materials, geological disaster research and application and other fields. In the process of testing materials such as geological rock masses, testing equipment such as CT scanning, triaxial shear seepage and triaxial testing are widely used. In the field of geotechnical engineering with many applications, because the rock triaxial test can be used to conduct research on slope stability, roadway (tunnel) surrounding rock maintenance, rock burst, earthquake effects, etc., therefore, the triaxial test is used in act...
