    PLAXIS 3D Tutorial 03: Loading of a suction pile

    Application PLAXIS 3D
    Version PLAXIS 3D
    Date created 04 October 2018

    In this lesson a suction pile in an off-shore foundation will be considered. A suction pile is a hollow steel pile with a large diameter and a closed top, which is installed in the seabed by pumping water from the inside. The resulting pressure difference between the outside and the inside is the driving force behind this installation.
    In this exercise, the length of the suction pile is 10 m and the diameter is 4.5 m. An anchor line is attached on the side of the pile, 7 m from the top. To avoid local failure of the pile, the thickness of the tube where the anchor line acts on the pile is increased. The soil consists of silty sand. To model undrained behaviour, an undrained stress analysis with undrained strength parameters will be performed.

    This exercise will investigate the displacement of the suction pile under working load. Four different angles of the working load will be considered. The installation process itself will not be modelled.
