Embodiment

[0022] Such as figure 1 As shown, the strain-type internal displacement tester for measuring the internal displacement of the geomechanical model provided by the present invention is composed of an internal displacement sensor 1, a strain gauge auxiliary machine 2 and a strain gauge host 3, wherein the internal displacement sensor 1 is a Or more than one, and connected with the strain gauge auxiliary machine 2 in a half-bridge self-compensation mode through the induction lead-out line 11 on it, the strain gauge auxiliary machine 2 is connected with the strain gauge host 3, and the strain gauge host 3 is set to half bridge Bridge self-complementary.

[0023] Among them, the strain gauge auxiliary machine 2 and the strain gauge main machine 3 can adopt the UCAM series strain gauge main machine and auxiliary machine produced by Kyowa Corporation of Japan, but the strain gauges produced by this company are not limited. In this embodiment, the UCAM-70A strain gauge auxiliary machi...

Abstract

The invention discloses a strain internal displacement tester for measuring the internal displacement of a geo-mechanic model, which is characterized in that the tester consists of a strain gauge host computer, a strain gauge secondary computer and internal displacement induction gauges, wherein the number of the internal displacement induction gauges is one or more; the internal displacement induction gauges are connected with the strain gauge secondary computer through induction leading-out wires in a mode of semi-bridge self-complementation; and the strain gauge secondary computer is connected with the strain gauge host computer. The strain internal displacement tester not only fills up the blank that no internal displacement tester for testing the geo-mechanic model exists in the prior art, but also contributes to the internal displacement variation process generated by variation of uncontinuous structures such as rock mass faults, fracture zones and weak intercalated layers along with overloaded multiples so as to provide the basis for evaluating the overall stability and safety degree of corresponding projects. The strain internal displacement tester has the advantages of skillful design, simple structure and precise test.

Description

technical field [0001] The invention belongs to the technical field of measuring devices, and in particular relates to a strain-type internal scale tester for measuring the internal displacement of a geomechanical model. Background technique [0002] With the rapid development and construction of large and medium-sized hydropower projects, more and more hydraulic structures, such as dams, workshops, tunnels, underground power stations and high slopes, will be built on rock foundations with complex geological structures or In the rock body, the anti-sliding stability of such buildings, the deformation and overall stability of the foundation, the stability of the high slope of the rock mass, and the stability of the surrounding rock of the underground structure are all things that must be understood and understood during the design and construction of hydropower projects. Master and solve problems. These problems can be solved by establishing a corresponding geomechanical mod...
