Abstract:
The paper presents results of an experimental study on the axial load bearing behavior of vibratory driven
full displacement piles in comparison with impact driven and cyclic quasi-static installed piles in dense
sand. The test setup and the measurement devices used to this end are explained. Subsequently, the results
of the axial loading like load settlement curves are shown and the impact of the installation method is
interpreted. The results presented in this work are mainly based on three installation methods: test series
one investigates axial behavior of vibratory driven piles, test series two describe the same cyclic pile
installation process but without dynamic influence wherein a special test setup developed to install the piles
cyclic quasi-static in the soil was used. A third test series carried out using the conventional impact pile
driving method served the purpose of not only comparing the results against vibratory driving, but also
aided in isolating the effects of dynamics inherent to the vibratory driving process
