Abstract

V originále

The actual trends in geotechnical engineering, concerning assessment of geotechnical problems by numerical analysis by Plaxis, Flac, ZSoil, Abaqus, Crisp or Midas require adequate input settings, values, parameters. In addition to sophisticated laboratory procedures, the main reason to support the use of field testing is continuous characterization of the testing profile, immediate evaluation of the characteristics and type of soil and determination of geotechnical parameters needed for constitutive models of soils. Conventional surveying methods like core boring with sample extraction for laboratory tests can offer only limited point information about rock environment. In geological environments with clayey and silty soils the most common in-situ testing methods are static penetration test CPTm, CPTu with piezocone, and seismic cone SCPT. Estimation of soil properties based on results of the penetration tests is reliable only if the probe is made with provided boreholes, supplemented by laboratory tests. Sample data from CPT examination of foundation conditions along the route R1 Nitra, west - Beladice - Tekovské Nemce are presented to show the calculation of parameters for advanced constitutive models of soils.
