Description

Technical Field

[0001] This application relates to the field of simulated fault displacement experiments, and in particular to a novel fault displacement device for different fault types under multiple angles. Background Technology

[0002] In the field of simulated fault displacement testing, fault displacement is the phenomenon of relative displacement of rocks along a fault plane in the Earth's crust. Faults can be classified into normal faults, reverse faults, and strike-slip faults according to their type. Most testing devices can simulate normal and reverse faults, and some can simulate fault displacement at multiple dip angles. However, actual fault displacement is often quite complex, limiting the ability of existing devices to simulate multiple fault types. Therefore, there is an urgent need for a device that can simulate fault displacement at multiple angles and of multiple types.

[0003] To reasonably simulate the impact of different fault displacements on the roadbed at multiple angles, the modular model box can change its size and tilt angle according to different requirements, decompose the complex displacement into displacements in three directions, and simulate complex fault displacements by applying different velocities in different directions. Summary of the Invention

[0025] The following will explain its structural features and workflow in detail, using both schematic diagrams and operational examples:

[0026] like Figures 1-7 As shown, this application discloses a novel fault displacement device for different fault types under multiple angles.

[0027] The horizontal rail is connected to the base 7 at the first end, and four pads 8 are arranged on the ground, in two sets.

[0028] like Figure 3 As shown, the lateral moving device includes an engine 9, a lateral threaded rod 10, a U-shaped plate 11, pulleys 12 and a fixed bearing 13. The engine 9 is fixed together with the base 7 by bolts. The lateral threaded rod 10 is arranged along the length of the horizontal rail 1, passes through the U-shaped plate 11, and is equipped with a fixed bearing 13 at its end. Four pulleys are fixed together with bolts inside the U-shaped plate 11, in two sets.

[0029] The bottom of the vertical rail 2 is connected to the U-shaped plate 11 by bolts, and the top is fixed by bolts with steel sections with the same cross-section as the short side. There are two sets in total.

[0030] like Figure 4As shown, the vertical moving device includes an engine 14, a vertical threaded rod 15, a shaped plate 16, and a pulley 17. The engine 14 is fixed to the bottom of the long side of the vertical rail 2 with bolts. The threaded rod 15 is arranged along the length of the vertical rail. The pulley 17 is placed in the rails on the two short sides of the vertical rail 2. The two shaped plates 16 and the pulley 17 are fixed with bolts. There are two sets of these.

[0031] The two ends of the guide beam 3 are connected and fixed by bolts and the irregular plate 16 of the vertical device.

[0032] like Figure 7 As shown, the cantilever 4 is welded into a whole by the main arm 18 and the secondary arm 19. Two pulleys 20 are fixed at the top with bolts. Bolt holes are reserved on the inner side of the main arm 18. A slot is provided at the top surface of the secondary arm 19. There are two sets in one type. The guide beam 3 passes through the top of the cantilever 4, so that the pulleys 20 are above the track of the guide beam 3.

[0033] like Figure 6 As shown, the modular model box includes a base plate, side plates, and upright plates 25. The base plate includes a base plate 1 21 and a base plate 22. Both base plate 1 21 and base plate 22 have rectangular holes at one end, with a bolt hole pre-drilled in the middle of base plate 22. The side plates include a left side plate 23 and a right side plate 24. The left side plate 23 is an acrylic plate with a bolt hole pre-drilled at the center of gravity. It has a tenon at the upper left corner and grid lines and scale lines on the surface for easy real-time observation. There are two sets of these plates. The right side plate 24 is similar. The upright plates 25 have tenons on both sides and the bottom edge. There are two sets of these plates. The base plate and side plates are spliced ​​together by the upright plates 25.

[0034] like Figure 5 As shown, the longitudinal moving platform consists of an engine 26, a threaded rod 27, a guide rail 28, and a moving platform 29. Both ends are fixed to the horizontal rail 1 by bolts, and the moving platform 29 is connected to the base plate 22 by bolts.

[0035] The longitudinal guide rail 5 has four pulleys 31 fixed to the bottom surface at both ends. The pulleys are placed in the horizontal rail 1. Two sliders 30 are set on the guide rail 5. The sliders 30 are connected and fixed to the vertical arm 6 above.

[0036] like Figure 7 As shown, the vertical arm 6 has pre-drilled bolt holes on its side, and the slider 30 has a slot on its top surface.

[0037] This application provides a method for using a novel fault displacement device for different fault types at multiple angles, including:

[0038] Calculate parameters such as fault dip angle and burial depth according to the required experimental model to determine the size of the model box. After determining the size of the model box, adjust the cantilever 4 to the calculated width of the model, insert the base plate 21 into the cantilever slot, and fix the side plates to the side of the main arm 18 with bolts. Finally, insert the upright plate 25 into the pre-reserved tenon slots of the base plate 21 and the side plates. Repeat the same process for the other half of the model box. The model box assembly is now complete.

[0039] The gearbox 35 is connected to the engine. Speed ​​and direction are input on the controller to control the moving device to move in the set direction. The center of the guide beam 3 is the origin, with the longitudinal direction as the X-axis (positive to the right), and the lateral and vertical directions as the Y and Z axes (positive forward and upward respectively). Inputting the speed in the X column indicates that the longitudinal moving device moves at the set speed; similarly, inputting the speed in the Y column indicates that the lateral moving device moves at the set speed; inputting the speed in the Z column indicates that the vertical moving device moves at the set speed; positive and negative signs indicate direction.

[0040] By inputting velocities in different directions, the model box shifts in different ways. The following uses a fault dip angle of 45° as an example to illustrate the shifting methods for normal faults, reverse faults, and translational faults.

[0041] Normal fault: Using the left plate as the upper plate, the model's displacement distance is calculated. Cantilever 4 is adjusted to its approximate position, and the model box is installed. Fine-tuning is performed using the scale on the side of the model box until the displacement distance on the scale is greater than the experimental displacement distance. Displacement filler is added to the model box, and the monitoring system is adjusted. Once everything is ready, appropriate speeds are entered into the Z and Y columns of the gearbox (35Y and 35Y columns), ensuring they are the same magnitude and negative in direction. After the displacement reaches the required distance, the stop button on the controller must be pressed. This concludes the normal fault displacement experiment.

[0042] Reverse Fault: Similar to normal fault simulation, after aligning the slots of cantilever 4 and vertical arm 6 to the same horizontal line, assemble the model box in the same manner. Input appropriate speeds in the Y and Z columns of the gearbox, ensuring they are the same size and in the positive direction. After shifting to the required distance, press the stop button on the controller. This concludes the reverse fault shifting experiment.

[0043] Translational fault displacement experiment: Before assembling the model box, adjust the slots to the same horizontal line. After fixing the model box, enter an appropriate speed in the X column. The direction is not limited. After moving to the required distance, press the stop button on the controller. This completes the translational fault displacement experiment.

[0044] This application uses a dip angle of 45° as an example to further illustrate three types of fault displacement: normal fault, reverse fault, and strike-slip fault. This application includes, but is not limited to, these three types of fault displacement; different velocities can be input in different directions to simulate more complex fault displacement.
