Representative values of geotechnical parameters derived from dynamic penetration test
Representative values of geotechnical parameters derived from dynamic penetration test
Dynamic penetration test is a relatively simple field test, which is frequently used for testing of soil resistance. From the results of this test, it is possible to derive physical and mechanical geotechnical parameters of coarse-grained soils, namely relative density, angle of shear strength and deformation modulus. The representative values of these parameters can be furthermore used in design of geotechnical structures. The new Eurocode 7 provides a set of equations that should be followed to establish the characteristic value if the data is considered sufficient. In this article the results of dynamic penetration tests, performed in the locality of the capital city of Slovakia, were used for determination of mechanical properties of Danube gravels. Afterwards, results were statistically processed, and characteristic value was estimated according to Eurocode 7. The characteristic values of geotechnical parameters were compared with traditional evaluation procedures, where the average value is determined for each soil layer.
