Description

Technical Field

[0001] This invention relates to the technical field of earthquake fault physical simulation devices, and more particularly to a simulation test device for a wide fault zone fracture zone. Background Technology

[0002] In current scientific research related to earthquake faults, physical simulation devices are crucial for simulating various earthquake fault conditions. However, existing physical simulation devices for simulating earthquake fault action mostly use shaking tables or drive devices to cause two boxes filled with test soil to shift and deform, thus simulating an earthquake fault. The width of the soil fracture zone simulated by this physical model is relatively narrow compared to tunnel models, while the width of the fracture zone produced by a real earthquake fault can be tens of times larger than the diameter of a tunnel. Therefore, existing earthquake fault simulation devices cannot accurately simulate earthquake faults with wide fracture zones.

[0003] Therefore, how to provide a simulation device that can provide a simulated fracture zone with a wide fracture zone is a technical problem that urgently needs to be solved in this field. Summary of the Invention

[0015] Compared with the prior art, the beneficial effects of the present invention are:

[0016] This invention provides a simulation test device for a wide fault zone fracture zone. A third box assembly is positioned between a first box assembly and a second box assembly, and the third box assembly is configured to contact both the first and second box assemblies, allowing it to move relative to them. A misalignment region is created within the third box assembly to form a test width for the model under test. When this simulation test device is applied to an earthquake fault simulation test, the first, second, and third box assemblies are filled with test soil. When a driving force parallel to the misalignment direction is applied to the first and second box assemblies via the test platform, the first box assembly and... Fault displacement will occur between the third and third box components, and fault displacement will also occur between the second and third box components. The fracture zone of the test soil formed by these two fault displacements has a wider fracture zone compared to the narrower soil fracture zone simulated by the displacement between two boxes in existing technologies. This helps in studying the impact of earthquake faults with a wide fracture zone on building engineering.

[0046] Example 1

[0047] Please see Figure 1Specifically, this implementation method of the wide fault zone fracture zone simulation test device is used to simulate earthquake faults in wide fault zone fracture zones. The wide fault zone fracture zone simulation test device is set on a test platform to drive the wide fault zone fracture zone simulation test device to conduct earthquake fault simulation tests on the test model 5. The wide fault zone fracture zone simulation test device includes a first box assembly 1, a second box assembly 2, a third box assembly 3, and a support assembly 4. The first box assembly 1 has a first receiving area; the second box assembly 2 has a second receiving area; the third box assembly 3 has a misalignment area. The third box assembly 3 is disposed between the first box assembly 1 and the second box assembly 2, and is in contact with the first box assembly 1 and the second box assembly 2 respectively. A first accommodating area, a second accommodating area, and a misaligned area are connected to form a total accommodating space for accommodating the test soil. The supporting component 4 is movably connected to the third box component 3 to support the third box component 3 and keep the third box component 3 at the same height as the first box component 1 and the second box component 2. The test model 5 passes through the first box component 1, the third box component 3, and the second box component 2 in sequence, so that the test part of the test model 5 is placed in the misaligned area, and the test width of the test model 5 is formed through the misaligned area. The third box component 3 can be misaligned relative to the first box component 1 and the second box component 2, and the misalignment direction of the third box component 3 relative to the first box component 1 and the second box component 2 is parallel to the driving direction of the test platform.

[0048] Specifically, this embodiment provides a wide fault zone fracture zone simulation test device. A third box assembly 3 is positioned between the first box assembly 1 and the second box assembly 2, and is configured to contact both the first and second box assemblies, allowing the third box assembly 3 to move relative to them. A misalignment region is created within the third box assembly 3 to form a test width for the model 5 under test. When this simulation test device is applied to an earthquake fault simulation test, the first box assembly 1, the second box assembly 2, and the third box assembly 3 are filled with test soil. When a driving force parallel to the direction of displacement is applied to the first and second box assemblies 1 and 2 respectively via the test platform, fault displacement will occur between the first and third box assemblies 1 and 3, and also between the second and third box assemblies 2 and 3. The fracture zone fracture zone formed by these two fault displacements in the test soil is significantly larger than that in the prior art. The simulated narrow soil fracture zone between two box-shaped structures exhibits a wider fracture zone, thus aiding in the study of the impact of earthquake faults with wide fracture zones on building engineering. A support component 4 is movably connected to the third box-shaped structure 3, providing support to the third box-shaped structure 3 while maintaining it at the same height as the first and second box-shaped structures 1 and 2, keeping it in a suspended state. This avoids slip resistance caused by contact with the ground or test platform during the experiment. Therefore, this invention provides a simulation test device for wide fracture zones, achieving the technical effect of simulating a wide fracture zone, thereby contributing to the study of the impact of earthquake faults with wide fracture zones on building engineering.

[0049] like Figure 3 and Figure 4 As shown, in one possible implementation, the third housing assembly 3 includes a plurality of segmented housings 31, which are in contact with each other to form a third housing assembly 3 with a misaligned area. One segmented housing 31 at one end of the third housing assembly 3 is in contact with the first housing assembly 1, and one segmented housing 31 at the other end of the third housing assembly 3 is in contact with the second housing assembly 2. The width to be measured is formed between one segmented housing 31 at one end of the third housing assembly 3 and one segmented housing 31 at the other end of the third housing assembly 3. Each segmented housing 31 is movably connected to the support assembly 4.

[0050] Furthermore, each segment box 31 is a rectangular tubular structure, with a first protruding edge 311 symmetrically arranged on both sides of the rectangular tubular structure. A hook 312 is provided at the edge of the first protruding edge 311, and a buffer area is formed on the hook 312. The hook 312 is movably connected to the support component 4, and the hook 312 can move relative to the support component 4 in the buffer area along the misalignment direction.

[0051] Specifically, the third box assembly 3 is configured to include several segmented boxes 31 that are in contact with each other in pairs. The segmented boxes 31 on both sides are in contact with the first box assembly 1 and the second box assembly 2 respectively. During the earthquake fault simulation test, after the first box assembly 1 and the second box assembly 2 are fixed on the test platform, the test platform drives the first box assembly 1 and the second box assembly 2 to move in opposite directions. This causes relative movement between the segmented boxes 31 in the third box assembly 3, thereby forming a fracture zone with the same width as the misalignment area of ​​the third box assembly 3. The width of this fracture zone is the width to be measured in the model 5 to be tested, thus expanding the simulated width of the fracture zone. By adjusting the number of segmented boxes 31, fracture zones of different widths can be simulated. Therefore, the appropriate number of segmented boxes 31 can be selected according to the test requirements, thereby increasing the functionality of the simulation test device. That is, by adjusting the number of segmented boxes 31 and the thickness of a single segmented box 31 (the narrower the single segmented box 31, the denser the degree of fracture), different degrees of fracture and different fracture widths of seismic faults can be simulated, making the test process more rigorous and the test results more accurate. By setting the first protruding edge 311 on both sides of the segmented boxes 31, the contact surface between the segmented boxes 31 is increased, thereby preventing soil loss in the misalignment area during the displacement of the segmented boxes 31. The height of the third box assembly 3 can be fixed by the movable connection of the hook 312 with the support structure, so that the third box is in a suspended state to avoid contact with the test platform and the formation of resistance. A buffer area is formed on the hook 312, and the hook 312 can move relative to the support assembly 4 in the direction of displacement within the buffer area.

[0052] Preferably, the third box assembly 3, composed of several segmented box bodies 31, forms an internal misaligned space for placing the soil required for the test. This misaligned area is connected to the first and second accommodating areas, together forming a larger total accommodating space for holding the test soil. Before the earthquake fault simulation test begins, an appropriate amount of test soil is filled into this total accommodating space. The test platform drives the first box assembly 1 and the second box assembly 2 to move in opposite directions, causing the test soil in the misaligned area to move and deform, forming a fracture zone. Thus, the fracture zone formed by the test soil in the misaligned space simulates a wider earthquake fault with a fracture zone, thereby improving the simulation effect.

[0053] like Figure 2 As shown, in one possible implementation, the first housing assembly 1 includes a first main housing 11 and a first housing 12. The first main housing 11 is a hollow first cuboid structure 111. The first cuboid structure 111 has a first upper opening and a first side wall opening. A first through hole 112 is provided on the side wall opposite to the first side wall opening. One end of the model to be tested 5 passes through the first through hole 112. The first housing 12 is disposed between the first main housing 11 and the third housing assembly 3, and is detachably connected to the first main housing 11. It is in contact with a segmented housing 31 at one end of the third housing assembly 3. The first main housing 11 and the first housing 12 are connected to form a first accommodating area.

[0054] Furthermore, the second housing assembly 2 includes a second main housing 21 and a second housing 22. The second main housing 21 is a hollow second cuboid structure 211 with a second upper opening and a second side wall opening. A second through hole 212 is provided on the side wall opposite to the second side wall opening, and the other end of the model to be tested 5 passes through the second through hole 212. The second housing 22 is located between the second main housing 21 and the third housing assembly 3, and is detachably connected to the second main housing 21. It is in contact with a segmented housing 31 at the other end of the third housing assembly 3. The second main housing 21 and the second housing 22 are connected to form a second accommodating area, and the first main housing 11, the first housing 12, the third housing assembly 3, the second housing 22 and the second main housing 21 together constitute the total accommodating space.

[0055] Furthermore, the first housing 12 is provided with a first opening, a second opening, and a third opening. The first opening is located at the top of the first housing 12. The cross section of the second opening is perpendicular to the bottom side wall of the first housing 12. The cross section of the third opening forms a first preset angle with the bottom side wall of the first housing 12. The cross section of the third opening is not adjacent to the cross section of the second opening. The cross section of the second opening is detachably connected to the cross section of the first side wall opening of the first main housing 11. The cross section of the third opening is in contact with a segment housing 31 at one end of the third housing assembly 3.

[0056] Furthermore, the second housing 22 is provided with a fourth opening, a fifth opening, and a sixth opening. The fourth opening is located at the top of the second housing 22. The cross section of the fifth opening is perpendicular to the bottom side wall of the second housing 22. The cross section of the sixth opening forms a second preset angle with the bottom side wall of the second housing 22. The cross section of the sixth opening is not adjacent to the cross section of the fifth opening. The cross section of the fifth opening is detachably connected to the cross section of the second side wall opening of the second main housing 21. The cross section of the sixth opening is in contact with a segment housing 31 at one end of the third housing assembly 3. The first preset angle and the second preset angle are the same size.

[0057] Specifically, the first main housing 11 and the second main housing 21 have the same structure, as do the first housing 12 and the second housing 22. The tops of the first main housing 11 and the second main housing 21 are set as openings, allowing observation of soil changes during the simulation test in the wide fracture zone. By setting detachable first housing 12 and second housing 22, and ensuring that the contact surfaces of the first housing 12 and second housing 22 with the third housing assembly are parallel to the fault plane of the fracture zone, the angle between the contact surface and the horizontal plane of the model under test can be adjusted by replacing the first housing 12 with a different first preset angle (the first preset angle is the same as the second preset angle). This provides fracture zones with different angles between the fault plane and the horizontal plane of the model under test, thus aiding in the study of their impact on the model under test.

[0058] Those skilled in the art will understand that, in order to maximize the relative displacement of the slippage and avoid soil loss during the slippage process, for the first box 12, a second convex edge can be formed by extending along the outer side of the cross section where the third opening is located on both sides of the third opening, so as to contact the first convex edge 311 of a segment box 31 at one end of the third box assembly 3 through the second convex edge; similarly, for the second box 22, a third convex edge can be formed by extending along the outer side of the cross section where the sixth opening is located on both sides of the sixth opening, so as to contact the first convex edge 311 of a segment box 31 at the other end of the third box assembly 3 through the third convex edge.

[0059] In one possible implementation, the support assembly 4 includes a cuboid support frame 41 and a plurality of support rods 42. The cuboid support frame 41 is mounted on the periphery of the third box assembly 3. The plurality of support rods 42 are parallel and symmetrically distributed on two opposite sides of the cuboid support frame 41. The number of support rods 42 is adapted to the number of hooks 312 of a segmented box 31, and the hooks 312 are correspondingly hung on the support rods 42.

[0060] In one possible implementation, the number of hooks 312 of a segmented box 31 can be set to four, symmetrically distributed on both sides of the segmented box 31. Correspondingly, the number of support rods 42 is set to four, symmetrically distributed on two opposite sides of the cuboid support frame 41. The four hooks 312 of a segmented box 31 are respectively hung on the four support rods 42. Those skilled in the art will understand that the hooks 312 and the support rods 42 are movably connected and have a certain amount of room for movement, so that the segmented boxes 31 in the third box assembly 3 can move relative to each other during the simulation test.

[0061] In one possible implementation, the width of the first through hole 112 is the same as the outer diameter of the model 5 to be tested, and the length of the first through hole 112 is greater than the outer diameter of the model 5 to be tested, so that the model 5 to be tested can move along the length direction of the first through hole 112; the height of the second through hole 212 is the same as the outer diameter of the model 5 to be tested, and the length of the second through hole 212 is greater than the outer diameter of the model 5 to be tested, so that the model 5 to be tested can move along the length direction of the second through hole 212.

[0062] It is possible to set the shape of the first through hole 112 and the second through hole 212 to be a through hole shape with semi-circular ends and a rectangular middle, so that the cylindrical test model 5 can be set at both ends of the first through hole 112 or the second through hole 212 without gaps. The length of the first through hole 112 and the second through hole 212 is set to be greater than the diameter of the test model 5, so that the test model 5 can move along the length direction of the second through hole 212.

[0063] In earthquake fault simulation tests, the test model 5 needs to maintain a certain distance from the sidewall of the test chamber, and the greater the distance, the better the simulation effect, in order to meet the boundary conditions. Since simulation tests are generally conducted in a laboratory, to achieve the simulation effect of a large-sized test chamber within a limited space using a small-sized chamber, the first chamber component 1 and the second chamber component 2 (without test soil) can be subjected to maximum displacement in a horizontal direction parallel to the section where the third opening is located before the test. That is, to adjust the test model 5 to a better position before the test, i.e., further away from the side requiring displacement, the first chamber component 1 and the second chamber component 2 can be moved a certain distance in the opposite direction of the required displacement before the test, such as... Figure 5 As shown, one end of the model to be tested 5 is located at the leftmost end of the first through hole 112 and the other end is located at the rightmost end of the second through hole 212, or one end of the model to be tested 5 is located at the rightmost end of the first through hole 112 and the other end is located at the leftmost end of the second through hole 212.

[0064] Before the experiment begins, the spatial positions of the first box assembly 1, the second box assembly 2, and the third box assembly 3 are adjusted to ensure that their internal spaces are interconnected and sealed on all sides. Then, an appropriate amount of test soil is filled into the total containment space. After the experiment begins, the test platform is displaced by the jacks, causing the first box assembly 1 and the second box assembly 2 on it to move in opposite directions. This causes the soil in the displaced space to fracture and deform accordingly. Thus, the soil in the displaced space can simulate a fault zone with the same width as the displaced space, improving the simulation effect.
