ANALYSIS OF EXISTING METHODS FOR DETERMINING INTERMEDIATE GEOTECHNICAL CHARACTERISTICS OF SOILS

Abstract

This article presents an overview of the main methods for determining the intermediate geotechnical characteristics of soils, emphasizing the importance of strict adherence to the testing regime. Deterministic and stochastic interpolation methods such as Thiessen polygons, inverse distance weighting (IDW), Spline and Kriging are discussed. Special attention is given to the problem of determining strength properties at various points, where only certain areas are to be investigated and intermediate values are obtained by interpolation methods. The analysis of geotechnical reliability using Kriging numerical models and methods of using geographic information systems for processing and presenting geotechnical data are also discussed.
