Wykorzystanie badań in situ w ocenie stanu podłoża organicznego

The paper presents an example of in situ testing to evaluate the geotechnical conditions performed for the organic subsoil of Antoniny embankment. The results obtained from cone penetration tests and dilatometer tests are presented. Results of cone penetration tests and dilatometer tests were compared with the laboratory test results. From an analysis of the results new factors to evaluate the preconsolidation pressure σ’p, the undrained shear strength τfu and modulus M of organic soils from the cone penetration test and the dilatometer test are proposed. Analysis of tests results indicates the usefulness of in situ testing in the evaluation of change in organic subsoil condition caused by embankment loading.
