Background

Undisturbed soil, also commonly referred to as undisturbed soil samples, is a soil sample that retains a natural water content and a natural structure. The method is used for measuring indexes such as volume weight, natural pore ratio, compression coefficient, shear strength and the like of soil. One of the main tasks of engineering geological drilling is to take core or undisturbed soil samples in the geotechnical layer. The natural structure of the sample should be maintained during the sampling process, and if the natural structure of the sample is destroyed, it is called a "disturbed sample". Perturbed samples are less tolerable in engineering geological surveys and are obsolete unless stated otherwise. The undisturbed sample of natural structure has core sample and soil sample, and the natural structure of core sample is difficult destruction generally, but soil sample is disturbed very easily.
