STUDY OF THE PENETRATION OF THE PROBE CONE INTO THE COMPACTED SOIL DURING STATIC PROBING
The article presents the results of an experimental and theoretical study of the penetration of the cone tip of the probe into the ground, used in widespread field tests of static sensing during geotechnical engineering surveys. A method for assessing the quality of compaction of erected road embankments has been developed. Experiments were carried out in a tray on model materials (metal balls) simulating high-density sandy soils. These experiments made it possible to identify the main patterns of behavior of the model soil when the probe cone penetrates into it, to propose a model of soil behavior and a calculation formula. The behavior of the sandy soil during the penetration of the probe cone, given in the literature, was also analyzed and a comparison was made with the above proposals, which made it possible to better evaluate the above results. The article concludes with the main conclusions.
