Сравнительный анализ зарубежных и отечественных методик расчета плотности песков по результатам статического зондирования

The determination of sand density is most commonly performed using the cutting ring method and the volume replacement method. However, the applicability of these techniques is constrained by factors such as depth of occurrence, depositional genesis, and the degree of soil saturation. Consequently, static cone penetration testing can be regarded as a more universal and practically accessible approach, providing sufficient accuracy for engineering applications.

In this study, the methodologies proposed by P.K. Robertson, P.W. Mayne, J. Peuchen and D. Bouwmeester, and L.G. Mariupolsky were examined. The analysis revealed that the formulas developed by P.K. Robertson and P.W. Mayne yield considerable discrepancies in estimating sand density (p) when
Rf < 0.6 %. Conversely, for Rf > 0.6 %, the computed density values tend to converge. The approach suggested by L.G. Mariupolsky provides intermediate results and is recommended for practical implementation.
