Numerical investigations on the deformation behavior of horizontal loaded injection piles

Today, driven piles are commonly used to fix offshore foundations for wind energy converters in the sea bed. However, the installation noise level due to pile driving is far beyond the limit which should be kept for the protection of marine life. Therefore, drilled injection piles are used in the steel structure of a newly developed foundation system. To consider the stiffness of the piles in the static and the fatigue design of this foundation system, numerical investigations for two soil conditions and 3 scours each are carried out. First results are presented in this article.
