Abstract

In the last three years the research program was conducted in the Czech Republic, which was aimed on the in-situ penetration tests results interpretation. Geotechnical engineers and statisticians from academic environment and engineering geologists from private companies dealing with geological survey were incorporated into the research team. The main objective of the research was to improve methodology of interpretation the dynamic penetration test (DPT) and cone penetration test (CPT) records. This was achieved through the specification of more accurate correlations between the values of parameters measured during a penetration test and geomechanical parameters of penetrated soils. The on-line database enabling direct statistical processing of big amount of archive data (more than 700 probes) was build first. Based on this database the new correlations were established. Correlations were next incorporated into the newly developed application for direct evaluation of measured data. New correlations are presented, and the process of their development is described in paper.
