    In this master’s thesis three-dimensional models of the analysed ground are presented. The data that was used in this thesis were obtained from twenty CTPU static probes which was carried out around four drilling boreholes. The data have been used to the project development NCBiR No. R09 0017 04/2008 on „Regional assessment of the geotechnical properties of land south-eastern Poland based on sounding and laboratory monitoring” (Rybicki et al., 2011). RockWorks software was used to generate models. Soil conditions in the area of Szczepanów were presented in the form of five solid models. The 3D models allowed visualization of ground conditions, which helps in assessing to the construction of the subsurface zone.

    Zastosowanie sondowania statycznego w badaniach prowadzonych w PPiEZRiG Petrobaltic S.A.
    (2006) Zajfert, Grzegorz
    Marine geotechnical investigations should be run for such investments as suspension of the platform, gas pipelines installment, anchoring of overflow-moor buoys to the tanker, and designing hydrotechnical objects. Petrobaltic used a penetrometer Roson 10 T, installed on a ship m/v St. Barbara. The Dutch Penetrometer Roson 10 T A.P. V.d. Berg enables soil analyses in situ. The methods lie in sticking measurement cones into the ground with simultaneous digital recording physical and mechanical parameters of the sediments. The sounder can be also equipped with cones CPT and CPTU, and tester MOSTAP-65 with which undisturbed samples can be collected. Specific parameters and ground properties are registered during the measurement. These parameters enable determination of the geotechnical profile and carrying capacity of the sediments. This device is indispensable for evaluating mechanical properties of grounds whenever intact samples cannot be collected, e.g. from sandy sediments. The paper provides descriptions of research processes, where various difficulties may be encountered. The Author presents his own solutions and experience in preventing failure or measurement errors.
