The finite element calculation of structural strength for a floating dock is critical to its
safety. In this article, a 115 m inland river floating dock is taken as the research object,
and the horizontal strength is calculated by direct calculation method. According to the
calculation, three measures to enhance its lateral strength are proposed, and the optimal
structural strengthening scheme is selected by fuzzy comprehensive evaluation method. Finally
the total longitudinal strength analysis of the floating dock is carried out, and the
strength of the dock when launching into water is directly analyzed by a finite element
simulation software to ensure its strength in the launching process.
