The present invention discloses an apparatus and method for artificially preparing structural soil samples capable of controlling the strength of their structural properties. The apparatus belongs to the field of geotechnical engineering and comprises a low-temperature forming module, a carbonization module, and a terminal device. The method, based on the apparatus, obtains the percentage of pores in each pore size interval of natural loess through a mercury intrusion test, air-dries and crushes the sample, adds CaO, and mixes uniformly. Distilled water is sprayed on the CaO-added soil material and stirred to generate Ca(OH)2, thereby preparing a mixed soil material. Dry ice pellets are prepared based on the percentage of pores in each pore size interval obtained through the mercury intrusion test, mixed uniformly with the mixed soil material, and pressed into a sample of the desired size. The sample is placed in a CO2 environment for curing, and CaCO3 cementation, similar to that of natural loess, is formed between the soil particles. The generated CaCO3 content controls the structural properties by varying the CaO incorporation ratio. Furthermore, the present invention enables non-destructive monitoring of the carbonization process during sample preparation and can control the moisture content of the prepared sample.
