“…However, its boundary conditions cannot be accurately controlled and cannot reflect the stress-strain relationship of soil in other stress-strain states. But by comparison, the boundary conditions of indoor test are relatively clear and easy to control, and the research results of soil indoor test are quite rich [3][4][5][6][7]. Remarkably, the preparation method of soil sample is an important factor affecting the determination results of soil laboratory test.…”

The difference of sample preparation methods will directly lead to the difference of the structure of the sample, and the mechanical response characteristics under external load will be different. Based on the conventional tests such as particle analysis, specific gravity, critical moisture content, and consolidation test of undisturbed loess from Xi’an, this paper focuses on the static triaxial consolidated drained shear and consolidated undrained shear tests on undisturbed and remolded loess. The results show that: (1) the structure has an obvious influence on the stress-strain relationship of the sample, the stress-strain curve of the undisturbed sample is a strain softening curve, and the stress-strain curve of the remolded sample is a weak strain hardening curve; (2) under the same loading conditions, the triaxial shear strength of the undisturbed soil is significantly higher than that of the remolded soil; (3) the change rule of the consolidation ratio of undisturbed and remolded samples is basically the same, but the final consolidation ratio of remolded soil is greater than that of undisturbed soil.

“…Expansive soil supplemented with coconut fibres has undergone several mechanical property tests. Peter carried out the triaxial and CBR experiments [10], Narendra et al noticed the expansive soil's UCS [18], Himanshu et al performed triaxial testing on clay soils [19], and Lal et al performed a triaxial test on sandy soil. Due to the normal behavior of soil, settlements, fissures, and other structural problems result.…”

An efficient and dependable method for enhancing the strength and stability of soils is soil reinforcement.Numerous studies have looked at how randomly oriented discrete inclusions (such as fibres, mesh components and waste materials like plastic strips and tyre pieces) affect highly compressible clayey soils.. In many parts of southern and coastal India, coir, a naturally biodegradable material, is used for construction. In the majority of these experiments, the Small samples were put through the triaxial test, C.B.R., unconfined compression and direct shear tests. The current work focuses on the effect of coir on bearing capacity and settling of footings employing parameters using laboratory model tests on highly compressible clayey soil reinforced with randomly dispersed coir fibre. such as the thickness of the reinforced layer with 0.25%, 0.5%, 0.75%, and 1.0% of coir. The capacity of the structure is increased by the inclusion of a reinforced layer made of coconut coir. The provision of a coir-reinforced layer, which was shown to be an economical technique among many types of bearing capacity improvement techniques, generally demonstrates that it decreases settlement and enhances bearing capacity.
