SIMILARITY TOPICS OF SOILS WITH SENSITIVITY TO WETTING BASED UPON DATA GATHERED FROM LABORATORY TESTS

Abstract

Special problems are occurred in several areas of Romanian territory, where intensive urbanization process involves the building foundations on soils with high sensitivity to wetting. The paper includes the data gathered from geotechnical laboratory tests carried out on samples collected from different sites located along Danube river shore. The aspects regarding similarity of geotechnical properties for identification and behavior were analyzed. The results have allowed establishing the variation intervals of certain parameters depending on depth and soil class, which have led to a statistical processing of data of data input. The research direction in which is part the present paper consists in creating a comprehensive database required for difficult soil zoning at national level and providing basic information for urban planning. Also, in the present context of sustainable development, it is imposes for an estimation of real foundation conditions and therefore the widespread use of correlations between physical indices, which define the soil nature and state, and mechanical ones, involved in assessment of foundation settlement or in estimation of bearing capacity of soil foundation.
