COMPARATIVE ANALYSIS OF THE USE OF PORE PRESSURE AND HUMIDITY IN ASSESSING THE IMPACT OF SOIL INDICATORS IN TRANSPORT CONSTRUCTION
Currently, there is a question of the reasonable applicability of pore pressure and humidity indicators in assessing the impact of soil indicators in various environments and conditions of transport construction. The hypothesis of a significant influence of thermal photons on the mechanical properties of gases can explain the behavior of the compressibility factor of gases. With an increase in the gas density, the compressibility factor increases because, along with an increase in the gas density, the number of photons that have a mechanical effect on the gas molecules also increases. As the temperature increases, the energy of thermal photons increases, so does the compressibility factor (the gas's resistance to compression). Since more energetic photons have a stronger mechanical effect (they push apart) on the gas molecules. That is why the compressibility factor increases in the temperature range from 10 K to 150 K. At temperatures of more than 150 K, the number of thermal photons that have a mechanical effect on the gas molecules decreases, because the radiation of the gas outside increases. Reducing the number of photons in the gas volume reduces the internal pressure of the gas and, accordingly, the compressibility factor decreases. The moisture index (corresponding to the concentration or density) used in the measurement of soil properties is more accurate and reliable (it has a greater proportion of the explained dispersion) and shows a more significant change in its properties in comparison with the pore pressure.
