Analysis of risk factors in the measurement of physical properties of soils

The determination of the physical properties of soil is the basis for the successful design and construction of engineering projects. These properties directly influence the behaviour of the soil under various loads, which determines the stability and safety of building structures. To date, the main challenges in this field are the high degree of uncertainty and the risk of errors in laboratory testing. This study presents an experimental study of the physical properties of soil and provides a discussion on the probabilities of error and inaccuracy risks for each of the methods presented. The risk analysis approach was used for the evaluation. The approach focused on quantifying the errors in the measurements and the soil test method. The results showed that all methods of testing the physical properties of soil require a high degree of accuracy and adherence to standards, but the soil compaction test is a more complex process that requires special care and rigour in the procedures.
