[0002] The transverse isotropic characteristic compacted clay preparation device is commonly used in the fields of civil engineering, geology and environmental engineering, especially in the study of the mechanical properties and behaviors of materials such as soil and clay. Transverse isotropic materials have physical properties that differ in one direction from other directions, which is common in materials such as clay. Compacted clay is often formed by layering and rolling, and has typical transverse isotropic characteristics, so that its fracture performance depends on the relationship between crack propagation direction and bedding plane. In the unilateral split beam SENB sample fracture experiment, the crack is at a 90-degree angle with the compacted layer, i.e., the compacted height is the experimental thickness.

[0003] As disclosed in Chinese patent publication No. (CN221765396U), a device for preparing two compacted clay NSCB samples simultaneously is disclosed, which includes a compacting plate and a sample container with a closed bottom and an open top. The interior of the sample container is divided into two sample preparation cavities by a vertically arranged middle baffle. Each sample preparation cavity is provided with a pre-crack pad. The compacting plate is located at the upper end of the interior of the sample container and is connected to a jack. The bottom surface of the compacting plate is provided with a clearance slot corresponding to the position of the middle baffle and facilitating the insertion of the upper end of the middle baffle.

[0004] In summary, the device also has the following technical problems: due to the size effect of the fracture process zone itself under different sample characteristic sizes, although the above-mentioned comparative patent can simultaneously prepare two compacted clay samples, when it is necessary to increase the specifications of compacted clay of different sizes, different size preparation devices need to be purchased, which causes the problem of increased use cost of compacted clay preparation devices. Therefore, it is necessary to propose a transverse isotropic characteristic compacted clay preparation device to solve the technical problems mentioned in the above patent and provide a new technical solution.
