The biopolymers were mixed evenly based on the specified mixing ratio of xanthan gum to guar gum, followed by mixing with clay in the container according to the designated amount. Water was sprayed into the container until reaching a predetermined level, and the mixture was stirred to achieve a uniform sample. Throughout the test, the concentration of xanthan gum and guar gum in the stabilized soil decreased with the addition of water, while the ratio between xanthan gum and guar gum in the stabilized soil remained constant.
To explore the engineering properties of clay treated with xanthan gum and guar gum composite materials, various tests including the Atterberg limit, compaction, and triaxial consolidation without drainage were carried out on both treated and untreated specimens. The mixing design for these tests is outlined in Table 3, with all tests conducted in accordance with GB/T50123-2019 [21] .
