| Geotechnical Investigations Analysis and Supervision Field borings : Determines soil profile, collects sample for laboratory analyses, determines the consistency of the soil layers¸posket penetrometer and share, SPT tests, water level, inclinometers, piesometersLaboratory Tests Unit weight determination, specific gravity test, water content determination, sieve analysis, Atterberg limits, unconfined compression test, direct shear test, triaxial test, consolidation test, CBR test, permeability test, compaction test and others Cone penetration test, dissipation tests Provides continuous data on cone resistance and frictional resistance. Using electric static cone penetrometer on truck with hydraulic trust of 20 metric tons, it is possible to penetrate layers of hard sand and grovels with SPT up to 50. Measuring pore pressure (CPTU) it is easy to define location and thickness cohesive and non-cohesive layers. With dissipation tests it is possible to define coefficient of consolidation and permeability. Maximum depth reached with this penetrometer was 76m in Mirna valley in Croatia. It is excellent tool for determining pile bearing capacity and evaluating strength characteristic of soil and soil parameters from the correlation Geotechnical reports and analysis |
