The paper presents some results of an experimental study on the cyclic lateral loaddisplacement behavior of vibratory driven monopiles in dense sand. The test setup and the measurement devices used are explained. Subsequently, the results of pore water and earth pressure measurement of three experiments are presented. These results are set in relation to the cyclic lateral load displacement behavior of the piles. The presented results are based on two tests with vibratory-driven piles; one with a cavitational and one with a non-cavitational vibration mode. In order to relate these experimental results to an usual monopile installation method, a third test with an impact driven pile is presented.
