Thrust fault construction physical simulation experiment device

Abstract

The invention discloses a thrust fault construction physical simulation experiment device. A formation model is arranged on a fixed flat plate. Clamp slots are arranged on front and rear ends of the fixed flat plate. A movable plate fixing seat is embedded in each clamp slot. A movable plate is arranged on each movable plate fixing seat, and the movable plate fixing seat is hinged with the movable plate. A motor and a screw are arranged on the bottom end in the experiment device table, and are corresponding to circular holes in the fixed flat plate. The motor is connected with the screw. A push rod is arranged on the upper end of the screw. The push rod is connected with the screw. A rotating gear is arranged in the experiment device table. A linear rack which matches the rotating gear is arranged on the upper end of the rotating gear. The rotating gear is connected with the motor. According to the invention, the state demonstration of the phenomena of wrinkles, breaks and the like caused by mutual compression between the screw rod and the push rod and between the formation model driven by gear and the rack and the movable plate is realized; the device has the advantages of safe and simple operation and high visibility; and the whole evolution process is easily observed.

Description

Technical field [0001] The invention relates to the technical field of experimental devices, in particular to a physical simulation experimental device for thrust fault structures. Background technique [0002] Thrust fault refers to the observable or inferred low angle along the rock ( <30°) The displacement surface produces a fault with a horizontal displacement greater than 5km. The exosomes covered on the thrust plane and moved more than 5km are called nappe or thrust mats. Thrust mat and nappe are often used synonymously, but nappe is more used for large-scale and distant foreign rock masses, while thrust mats can be large or small in scale, and are mostly flat output. [0003] The physical simulation experimental device of thrust fault structure is a new type of fracture formation simulation device, and its purpose is to apply it to scientific research and teaching. At present, there are relatively few structural physical simulations of thrust fault activity and associa...

AI Technical Summary

Problems solved by technology

At present, there are few structural physical simulations of thrust fault activity and associated fracture development at home and abroad, and the devices generally have the following deficiencies: First, the visibility of the fault formation process is poor, which cannot meet the requirements of experimental researchers for fault activity and associated fracture development. Monitoring of fracture development and evolution; second, the control accuracy of existing simulation devices is low; third, most of the existing simulation devices have complex structures, high cost of use, and unsafe operation
