Abstract

The invention relates to a system for simulating, loading and measuring the complex deformation of a geological soft material. The system comprises a loading unit, a control unit and a deformation measuring unit, wherein the loading unit is used for receiving a signal from the control unit, performs loading operation on a test piece to be measured by matching the signal with a result of the deformation measuring unit, and feeds loading information back to the control unit; the control unit is used for controlling the loading unit and the deformation measuring unit and receiving the loading information fed back by the loading unit and deformation information on the surface of the test piece, which is fed back by the deformation measuring unit; and the deformation measuring unit is used forreceiving the signal from the control unit, acquiring a digital speckle image on the surface of the test piece according to a time sequence when the deformation measuring unit is matched with the loading unit according to the signal to load the test piece and is subjected to stipulated displacement action, analyzing the digital speckle image and feeding the deformation information on the surface of the test piece back to the control unit. The system for simulating, loading and measuring the complex deformation of a desktop small geological soft material can conveniently simulate the complex deformation of the geological soft material and quantitatively and accurately measure full-field deformation.

Description

Technical field [0001] The invention relates to a system for simulating loading and measuring the deformation of geological soft materials, in particular to a system for simulating loading and measuring the complex deformation of geological soft materials. Background technique [0002] Crustal rocks will undergo very complex deformation and destruction under the long-term action of tectonic movement. This process has two distinct characteristics: one is that the action process is very long, and its action time is often millions of years; the other is that the loading process is relatively complicated. , Is a multi-directional and time-varying non-steady loading. Under this complex action, the crustal rock medium will undergo very complicated deformation and fracture. Understanding this complex deformation process is of great significance to the understanding of the formation mechanism of geological structures, and therefore it is very important for various minerals and oil and g...
