Problems solved by technology

For the existing geological structure simulation test benches, most of them can only simulate vertical structural stress, and are limited to simulate faults, and most of them are simulations with fixed dimensions and inclination angles. They can only realize the control mode of single movement, and cannot realize the simultaneous movement of multiple regions.
For the simulation of horizontal structural movement, the method theory is immature, the experimental equipment is not perfect, and the flexibility is poor

Embodiment 2

[0069] This embodiment simulates a reverse fault, and the device for simulating a reverse fault is as follows image 3 As shown, it is the same as in Example 1. Firstly, the bottom layer of similar material E is laid. After E is laid, a water bag is laid on top of E, the above two smooth boards are laid on the top of the water bag, and D and C are laid on top of the smooth board in turn. , B, and A are similar material layers, and the two are slightly different in the specific test method. The difference from Example 1 is that in the specific test method, in the fifth step, the present embodiment is to remove the partition and the lower end of the fault. Click the smooth plate on the left part to simulate the formation and evolution process of the reverse fault structure.

Abstract

The invention discloses a simulation test apparatus of a tectonic stress field and a method thereof. The apparatus comprises a simulated test bench, a loading module arranged at the top of the test bench, lateral loading systems, and a console. The simulated test bench includes a cuboid frame and baffle plates installed at the periphery of the cuboid frame. A model is laid inside the frame and is formed by successively laying of a plurality of layers of similar materials; and a water capsule and a smooth plate assembly are arranged between the bottom similar material and the similar material at the upper layer. The smooth plate assembly includes at least two smooth plates and a clamp groove part enabling the smooth plates to move relatively; and the water capsule is laid below the smooth plates. At least one separator plate for simulating a facture layer is arranged inside the similar material layer above the smooth plates in advance; and a certain included angle is formed between the separator plate and the water capsule at the horizontal direction. According to the invention, quantitative researches on the stress field evolution process during the tectonic movement formation process can be realized; and a beneficial theory and data basis can be provided for underground activities like mining.

Description

technical field [0001] The invention relates to a test device and method for the formation and evolution of rock geological structures, which is an experimental instrument for simulating stress field changes in the process of geological structure evolution through simulation experiments, especially for simulating and studying the evolution characteristics of stress fields in the process of fault and fold formation . Background technique [0002] With the increasing development of underground engineering such as human mining, geological structures such as faults and folds have brought huge obstacles to the further development of underground production activities and caused serious safety accidents. Therefore, it is imperative to fully understand the derivation law of underground structures and the distribution of stress field for the safe and scientific production of underground engineering. However, the research methods on geological structures at this stage still remain at...
