DETAILED DESCRIPTION

[0026] This application is based on the inventor's discovery and understanding of the following facts and problems:

[0027] In the model test box for active fault zone simulation test in the related technology, the force and movement of the specimen are easily restricted by the model test box, resulting in a single force direction, making it difficult to simulate complex force conditions and difficult to flexibly adjust according to test requirements.

[0028] Specifically, the model test box for active fault zone simulation test in related technologies is an integrated rigid structure. On the one hand, it will limit the force and movement of the specimen, resulting in a single force direction for the specimen, making it difficult to meet the test requirements for complex stress conditions. On the other hand, the integrated structure is difficult to make local adjustments according to the test requirements and has poor flexibility.

[0034] The sample 10 is cast from a test mix material. It should be understood that the test mix material is a material that is a mixture of simulated rock components and a curing agent for testing, and those skilled in the art can adjust its components and proportions according to actual needs.

[0035] The sample 10 is suitable for being cast in the box, and the length direction of the box is oriented along the front-to-back direction (the up-down, left-right and front-to-back directions are shown by arrows in the figure).

[0036] The box body includes an upper force-bearing plate 21, an upper front connecting frame 221, an upper rear connecting frame 222, a front end plate 231, a rear end plate 232, a front bottom plate 241, a rear bottom plate 242, a left connecting frame 251, a right connecting frame 252, a left front force-bearing plate 261, a left rear force-bearing plate 262, a right front force-bearing plate 263 and a right rear force-bearing plate 264.

[0037] The upper force-bearing plate 21 is suitable for fitting with the upper surface of the sample 10, the upper front connecting frame 221 and the upper rear connecting frame 222 are detachably connected to the upper surface of the upper force-bearing plate 21, the front end plate 231 is suitable for fitting with the front end surface of the sample 10, the rear end plate 232 is suitable for fitting with the rear end surface of the sample 10, the front edge of the upper front connecting frame 221 is detachably connected to the upper edge of the front end plate 231, the rear edge of the upper rear connecting frame 222 is detachably connected to the upper edge of the rear end plate 232, the front bottom plate 241 and the rear bottom plate 242 are suitable for fitting with the lower surface of the sample 10, the front edge of the front bottom plate 241 is connected to the lower edge of the front end plate 231, the rear edge of the rear bottom plate 242 is connected to the lower edge of the rear end plate 232, the left front The force-bearing plate 261 and the left rear force-bearing plate 262 are suitable for fitting with the left side surface of the sample 10, the right front force-bearing plate 263 and the right rear force-bearing plate 264 are suitable for fitting with the right side surface of the sample 10, the left connecting frame 251 is detachably connected to the left side surfaces of the left front force-bearing plate 261 and the left rear force-bearing plate 262, the front edge of the left connecting frame 251 is detachably connected to the left edge of the front end plate 231 and the rear edge is detachably connected to the left edge of the rear end plate 232, the right connecting frame 252 is detachably connected to the right side surfaces of the right front force-bearing plate 263 and the right rear force-bearing plate 264, the front edge of the right connecting frame 252 is detachably connected to the right edge of the front end plate 231 and the rear edge is detachably connected to the right edge of the rear end plate 232.

[0038] The flexible support assembly 30 includes a front support frame 31, a rear support frame 32, a plurality of sword-shaped links 33 and a plurality of sheath-shaped links 34. The front support frame 31 is connected to the rear edge of the front bottom plate 241, and the rear support frame 32 is in contact with the front edge of the rear bottom plate 242. The plurality of sword-shaped links 33 are rotatably arranged on the front support frame 31 and the axis of rotation is oriented in the up-down direction. The plurality of sword-shaped links 33 are arranged on the front support frame 31 at intervals along the left-right direction. The plurality of sword-shaped links 33 are parallel to each other. The plurality of sheath-shaped links 34 are rotatably arranged on the rear support frame 32 and the axis of rotation is oriented in the up-down direction. The plurality of sheath-shaped links 34 are arranged on the rear support frame 32 at intervals along the left-right direction. The plurality of sheath-shaped links 34 are parallel to each other. The plurality of sword-shaped links 33 are slidably and detachably matched in the plurality of sheath-shaped links 34 in a one-to-one correspondence. It should be understood here that "sword-shaped" and "sheath-shaped" are only for the convenience of describing the matching mode of the two, and are not a limitation on their shapes. Specifically, the sword-shaped connecting rod 33 may be substantially in the shape of a long flat strip with a free end in an arc shape, and the sheath-shaped connecting rod 34 may be substantially in the shape of a long flat strip with a slot adapted to the sword-shaped connecting rod 33 .

[0039] Specifically, the relative sliding and rotation of the sword-shaped connecting rod 33 and the sheath-shaped connecting rod 34 can avoid limiting the forces in other directions while providing support in the direction of gravity.

[0040] For example, when the reverse impact test is performed, the specimen 10 is subjected to force in the front-rear direction, and the sword-shaped connecting rod 33 and the sheath-shaped connecting rod 34 can be relatively telescopically slidable to avoid limiting the force on the specimen 10, so that the loading force is fully transmitted to the specimen;

[0041] When performing a slip test, the sample 10 is subjected to force in the left and right directions, and the sword-shaped connecting rod 33 and the sheath-shaped connecting rod 34 can rotate relative to the front support frame 31 and the rear support frame 32. At the same time, the sword-shaped connecting rod 33 and the sheath-shaped connecting rod 34 can be telescopically slid to avoid limiting the force on the sample 10 and ensure that the loading force is fully transmitted to the sample.

[0042] First, the box and the flexible support assembly 30 are assembled, and the sample 10 is cast in the box. After the sample 10 is solidified, the upper front connecting frame 221, the upper rear connecting frame 222, the left connecting frame 251 and the right connecting frame 252 are removed. The test is started, and force is applied to the sample 10 according to the test requirements.

[0043] According to the flexible model test box 1 for the active fracture zone simulation test according to the embodiment of the present invention, the box body includes an upper force-bearing plate 21, an upper front connecting frame 221, an upper rear connecting frame 222, a front end plate 231, a rear end plate 232, a front bottom plate 241, a rear bottom plate 242, a left connecting frame 251, a right connecting frame 252, a left front force-bearing plate 261, a left rear force-bearing plate 262, a right front force-bearing plate 263 and a right rear force-bearing plate 264. Compared with the one-piece model test box in the related art, the box body can adopt a modular design, which is convenient for adjusting the local part of the box body according to the test requirements, thereby improving the flexibility and applicability of the test.

[0044] Furthermore, by making the front edge of the upper front connecting frame 221 detachably connected to the upper edge of the front end plate 231, the rear edge of the upper rear connecting frame 222 detachably connected to the upper edge of the rear end plate 232, the left connecting frame 251 detachably connected to the left side surface of the left front force plate 261 and the left rear force plate 262, the front edge of the left connecting frame 251 detachably connected to the left edge of the front end plate 231 and the rear edge detachably connected to the left edge of the rear end plate 232, the right connecting frame 252 detachably connected to the right side surface of the right front force plate 263 and the right rear force plate 264, the front edge of the right connecting frame 252 detachably connected to the right edge of the front end plate 231 and the rear edge detachably connected to the rear end plate 2 The right edge of 32 is detachably connected, so that the upper front connecting frame 221, the upper rear connecting frame 222, the left connecting frame 251 and the right connecting frame 252 can be detached. In this way, after the sample 10 is cured, the upper front connecting frame 221, the upper rear connecting frame 222, the left connecting frame 251 and the right connecting frame 252 can be removed, and the sample 10 can only rely on the upper force plate 21, the left front force plate 261, the left rear force plate 262, the right front force plate 263 and the right rear force plate 264 to assist in the force bearing of the sample 10, eliminating the restrictions of the connecting frame on the force direction and force position of the sample 10, avoiding the problem of a single force direction of the sample 10, making the test results closer to the actual situation, and improving the accuracy of the test results.

[0045] In addition, by setting up the flexible support component 30, not only can the sample 10 be supported, but the flexible support component 30 can also be used to support the sample 10 in the direction of gravity, thereby preventing the middle part of the sample from being damaged due to its own weight and preventing the influence of gravity on the test results during the test. Moreover, by rotatably setting the sword-shaped connecting rod 33 and the sheath-shaped connecting rod 34, the sword-shaped connecting rod 3 can be slidably and detachably engaged in multiple sheath-shaped connecting rods 34, thereby avoiding the flexible support component 30 from limiting the force on the sample 10, ensuring that the loading force fully acts on the sample 10, and improving the accuracy of the test data.

[0046] Therefore, the flexible model test box 1 for the active fracture zone simulation test according to the embodiment of the present invention has the advantages of avoiding limiting the force on the specimen, good flexibility, strong applicability, high accuracy, etc.

[0047] The following describes a flexible model test box 1 for an active fracture zone simulation test according to a specific embodiment of the present invention with reference to the accompanying drawings.

[0048] In some specific embodiments of the present invention, Figure 1-Figure 5 As shown, the flexible model test box 1 for active fracture zone simulation test according to an embodiment of the present invention includes a specimen 10 , a box body and a flexible support assembly 30 .

[0049] Advantageously, if Figure 1-Figure 3 As shown, the flexible model test box 1 for active fracture zone simulation test also includes a front partition 41 and a rear partition 42. A first front slot 211, a second front slot 212, a first rear slot 213 and a second rear slot 214 are provided on the upper force plate 21. The first front slot 211, the second front slot 212, the first rear slot 213 and the second rear slot 214 are all oriented in the left-right direction and are spaced apart in the front-back direction. The first front slot 211 is located in front of the second front slot 212, and the first rear slot 213 is located behind the second rear slot 214.

[0050] The front partition plate 41 is detachably fitted into one of the first front slot 211 and the second front slot 212 , and the rear partition plate 42 is detachably fitted into one of the first rear slot 213 and the second rear slot 214 .

[0051] When the front partition 41 is engaged in the first front slot 211 and the rear partition 42 is engaged in the first rear slot 213, a front original rock casting area is formed between the front partition 41 and the front end plate 231, and a rear original rock casting area is formed between the rear partition 42 and the rear end plate 232.

[0052] When the front partition 41 is engaged in the second front slot 212 and the rear partition 42 is engaged in the second rear slot 214, a front fracture influence zone casting area is formed between the front partition 41 and the front original rock casting area, a rear fracture influence zone casting area is formed between the rear partition 42 and the rear original rock casting area, and a fracture crushing zone casting area is formed between the front fracture influence zone casting area and the rear fracture influence zone casting area.

[0053] The sample 10 includes a front original rock zone 11, a rear original rock zone 12, a front fault influence zone 13, a rear fault influence zone 14 and a fault crushing zone 15. The front original rock zone 11 is suitable for pouring in the front original rock pouring area, the rear original rock zone 12 is suitable for pouring in the rear original rock pouring area, the front fault influence zone 13 is suitable for pouring in the front fault influence zone pouring area, the rear fault influence zone 14 is suitable for pouring in the rear fault influence zone pouring area, and the fault crushing zone 15 is suitable for pouring in the fault crushing zone pouring area.

[0054] Specifically, the structural strength of the original rock zone is greater than that of the fault influence zone, and the structural strength of the fault influence zone is greater than that of the fault crushing zone to simulate a more realistic geological situation.

[0055] After the box body is assembled, the front partition 41 is first inserted into the first front slot 211, and the rear partition 42 is inserted into the first rear slot 213 to form a front original rock belt casting area and a rear original rock belt casting area. The front original rock belt 11 is cast in the front original rock belt casting area, and the rear original rock belt 12 is cast in the rear original rock belt casting area.

[0056] After the front original rock band 11 and the rear original rock band 12 are solidified, the front partition 41 and the rear partition 42 are taken out, the front partition 41 is inserted into the second front slot 212, and the rear partition 42 is inserted into the second rear slot 214. A front fracture influence zone casting area is formed between the front partition 41 and the front original rock band 11, and a rear fracture influence zone casting area is formed between the rear partition 42 and the rear original rock band 12. The front fracture influence zone 13 is cast in the front fracture influence zone casting area, and the rear fracture influence zone 14 is cast in the rear fracture influence zone casting area.

[0057] After the front fracture influence zone 13 and the rear fracture influence zone 14 are solidified, the front partition plate 41 and the rear partition plate 42 are taken out, and a fracture and crushing zone casting area is formed between the front fracture influence zone 13 and the rear fracture influence zone 14, and the fracture and crushing zone 15 is cast in the fracture and crushing zone casting area.

[0058] Specifically, Figure 1-Figure 3 As shown, the upper front connecting frame 221 is located in front of the first front slot 211, and the upper rear connecting frame 222 is located behind the first rear slot 213. In this way, the upper front connecting frame 221 and the upper rear connecting frame 222 can avoid interference with the front partition 41 and the rear partition 42, and facilitate the disassembly and assembly of the front partition 41 and the rear partition 42.

[0059] More specifically, Figure 1-Figure 3 As shown, the left front force plate 261 is located in front of the first front slot 211 in the front-to-back direction, the left rear force plate 262 is located behind the first rear slot 213 in the front-to-back direction, the right front force plate 263 is located in front of the first front slot 211 in the front-to-back direction, and the right rear force plate 264 is located behind the first rear slot 213 in the front-to-back direction. In this way, the left front force plate 261 and the right front force plate 263 can be correspondingly arranged on both sides of the front original rock belt 11, and the left rear force plate 262 and the right rear force plate 264 can be correspondingly arranged on both sides of the rear original rock belt 12. After the left connecting frame 251 and the right connecting frame 252 are removed, the force of the front fracture influence zone 13, the rear fracture influence zone 14 and the fracture and crushing zone 15 will not be limited, and the force of the front original rock belt 11 and the rear original rock belt 12 can be assisted, so that the loading force is fully applied to the front fracture influence zone 13, the rear fracture influence zone 14 and the fracture and crushing zone 15.

[0060] Figure 4 and Figure 5 The flexible model test box 1 for the active fracture zone simulation test according to some examples of the present invention is shown.
