中文摘要：

为深化高桩码头承载特性的研究,运用有限元软件ABAQUS对高桩码头进行7个工况下的三维数值模拟.研究发现：整个码头的位移以向海侧为主;产生向海侧位移的主要因素是堆场载荷,前后承台上的竖向载荷的影响相对较小;各工况中桩身向海侧的位移在20 mm以内;桩入土段的弯矩很小,在土体以上的悬空段的桩身弯矩较大,最大值的绝对值在45 kN·m以内.结果表明,基于ABAQUS的三维有限元模拟可成为高桩码头承载特性研究的有效途径.

英文摘要：

To further research the bearing characteristics of high-pile wharfs, based on the finite element software ABAQUS, 3D numerical simulations of a high-pile wharf under 7 operating conditions are done. It is found that, the displacement of the entire wharf is mainly towards the sea side ; the yard load is the main factor leading to the displacement towards the sea side, and the influence of the vertical load on the platform is relatively small ; the displacement of the pile towards the sea side is no more than 20 mm ; the bending moment of the pile in the soil is very small, while the bending moment for the pile out of the soil is larger, whose maximum absolute value is within 45 kN ~ m. The conclusion can be drawn that the ABAQUS-based 3D finite element simulation is an effective method to the bearing characteristic research of high-pile wharfs.
