Correlations of Regional Geotechnical Parameters on the Basis of CPTU and DMT Tests

Abstract

The requirements for field research for Polish conditions demand proper dependences. Dependences based on more than 30 localizations for different genetic types of soils were derived for the area of Poland. Direct results from CPT, DMT and profiles from boreholes have been collected at the test sites for individual localization. For interpretation of results, dependences and diagrams of CPTU versus DMT were created. Correlations on the background of results from literature for different types of soils for numerous research areas were collected, with established dependences for Polish grounds conditions. Additionally some recommendations for the interpretation of the results from CPTU and DMT tests for analysed soils have been proposed.
