Field method soil investigation includes such types of tests as punching test, pressiometry test, and direct shear test in field conditions, CPT (Cone Penetration Test), SPT (Standard Penetration Test), pouring into pits, flowmeter survey and pumping.

  • Punching test
  • CPT
  • SPT
  • Pressiometry test

Field methods concentrated on studying the physical-mechanical and filtration properties of arrays soil . For more informative studies, the accuracy and reliability of the geotechnical study of the engineering-geotechnical surveys should include field methods of soil investigation. The advantage of field research is their scale . The information which geotechnical engineer receives after field research provides an answer to the question about the structure of the array of soils, deformation and strength properties as well as its filtration properties.
