Normal Fault Simulation Device with Adjustable Dip Angle and Fracture Position

The device is divided into independent functional modules: a model box for containing the experimental material, a loading mechanism for applying stress, an angle adjusting mechanism for controlling fault dip angle, and a positioning mechanism for controlling fracture initiation position. Each module can be independently adjusted and configured, allowing flexible simulation of different fault types without requiring an entirely complex structure.

The device is designed to simulate multiple fault types (normal faults, reverse faults, strike-slip faults) and various geological conditions through a universal structure that can be reconfigured. The same basic device can accommodate different experimental materials, loading conditions, and geometric configurations, making it multi-functional for diverse fault simulation purposes.

The device incorporates dynamic adjusting mechanisms that allow the fault plane angle and fracture initiation position to be changed during or before the experiment. The angle adjusting mechanism enables modification of the dip angle, while the positioning mechanism allows adjustment of where the fault will initiate. This dynamic capability provides control flexibility without requiring an entirely complex fixed structure.

The device allows change in key parameters such as the dip angle of the fault plane and the position of the fracture initiation point. By enabling these parameters to be adjusted, the device can adapt to different experimental requirements while maintaining a relatively simple overall structure. The mechanisms allow continuous or discrete adjustment of these critical parameters.

The device enables the experimental material to naturally form faults through stress-induced fracturing rather than requiring artificial fault plane creation. The loading mechanism applies stress to the material, and the fault forms naturally as a result of the stress distribution and material properties. This self-service approach allows the material to behave according to its inherent characteristics and actual fault formation mechanisms.

The device replaces artificial mechanical fault creation methods with a stress-based approach where faults form naturally through mechanical stress application. Instead of manually creating fault planes, the system uses controlled loading to induce natural fracturing, substituting the mechanical act of fault creation with a stress-driven process that better reflects natural fault formation.

The device is designed to simulate multiple fault types and complex fault zone conditions within a single experimental setup. By adjusting the angle and positioning mechanisms, the same device can reproduce different fault configurations without requiring multiple separate experiments. This multi-functionality allows complex fault zones to be simulated in one experiment, reducing time consumption while maintaining accuracy.

The device allows preliminary adjustment and configuration of the fault plane angle and fracture initiation position before the actual experiment begins. By pre-setting these parameters according to the specific fault zone being simulated, the experiment can proceed directly to the simulation without requiring multiple trial runs or sequential experiments, thereby reducing overall time consumption.
