A bi-directional dynamic physical simulation experiment device and method for high gravity environment

Abstract

The invention discloses a bi-directional dynamic physical simulation experiment device and an experiment method for a high-gravity environment. The experiment device comprises an experiment box and apower device. The experiment box is composed of a fixed plate located on the front and rear sides and a movable plate located on the left and right sides, wherein the fixed plate and the movable plateare vertically arranged, the test material is arranged in the test box, and the two side walls of the movable plate move back and forth along the fixed plate under the action of the power device, soas to squeeze the test material in the deformation test box. Under the condition of constant gravity, the experiment device of the invention completes the arrangement of the experiment materials in the deep-seated structure physical simulation experiment box; Under the condition of centrifugal force, the bi-directional dynamic device of the tectonic physics simulation experiment box is automatically controlled, so that the deep tectonic physics simulation experiment is completed in the tectonic physics simulation experiment box, and the physical simulation experiment process of the bi-directional dynamic tectonic deformation in the experiment box is studied, which provides the real-time geological tectonic evolution process model for the researchers.

Description

Technical field [0001] The invention relates to an experimental device and an experimental method, in particular to a bidirectional dynamic physical simulation experimental device and an experimental method used in a supergravity environment. Background technique [0002] The physical simulation of geological structure has a research history of more than two hundred years. Research in this field has not been substantively developed until the establishment of the similarity theory in the 1930s (Hubbert, 1937), and eventually became the most important method for the study of geological structure deformation laws, formation processes and genetic mechanisms. For a long time, people The use of normal gravity structural physical simulation equipment has carried out a comprehensive study of the geological structure process, which has greatly promoted the research and understanding of structural geology. Especially since the mid-1980s, the physical simulation of structural deformation ha...

Problems solved by technology

[0005] Carrying out the simulation experiment in the supergravity environment of the centrifuge is an effective way to solve the problems existing in the physical simulation experiment of the constant gravity structure. Lower, smaller drum centrifuges

Although the highest gravitational acceleration of these drum-type centrifuge geological structure simulation devices can reach more than 1000g, the size of the experimental model is extremely small (up to more than ten centimeters, it is difficult to simulate the actual geological structure phenomenon in detail, and due to the small space of the experimental cabin, it cannot be used as usual. It is difficult to precisely control the deformation rate and record the whole process of deformation simultaneously as the gravity experiment device is equipped with force-applying components and real-time observation instruments.
