Abstract: In the work, on the basis of the analysis of tabular data of both current and former normative documents on engineering-geological surveying and design of soil bases and foundations of structures and literary sources, as well as own experience, a graphical and analytical interpretation of determination of the basic values of physical-mechanical normative and calculated indices of sandy soils according to the indicators of static q, MPa and dynamic RD, MPa probing are given. The use of the proposed empirical analytical dependencies can significantly accelerate the processing of field engineering-geological surveying and provide more objective comparison of such soils condition at different objects while making design decisions. They can also be used in the development of resident software, in case of its development and manufacture for automatically calculating the values of the physical and mechanical parameters of sandy soils. The obtained analytical dependencies are presented in the form of two tables for different types of sandy soils: separately for surveying that are carried out using both static and dynamic probes. And the graphs allow you to visually compare these dependencies, that can provide new material for further scientific generalizations and conclusions in the field of soil science and mechanics.
