| 摘 要： | 基于ANSYS/LS-DYNA应用软件,采用显式时间积分瞬态非线性有限元技术,对5 000 t级件杂货船分别在2 m/s和5 m/s 2种撞击速度的情况下,与3万t泊位高桩码头的碰撞过程进行数值模拟。获得了高桩码头上部结构的位移,以及接触区域应力应变的变化,分析了桩基在不同速度下的破坏情况和承载能力,得出了一般的规律和特点。

| Abstract: | Based on ANSYS/LS-DYNA software,the explicit time integration for nonlinear transient finite element technology was used in this paper.The collision processes of multipurpose ship(5 000 DWT)with two speeds(2 m/s,5 m/s)and high-pile wharf(30 000 DWT)were numerically simulated.Then the superstructure displacement of high-pile wharf and the stress-strain of contact zone were obtained and analyzed.The damage situation and bearing capacity of pile foundation were also analyzed to get the general rules and characteristics. |

| Keywords: | ship collision high-pile wharf numerical simulation stress-strain |
