| 摘 要： | 利用大型有限元计算软件ANSYS的参数化语言APDL进行二次开发,对波浪上托压强作用下桩基-重力式复合结构码头面板的动力特性进行研究,结果表明:1)波浪缓变压强作用下码头面板内力的动静力计算结果基本相等,缓变压强的动力放大作用很不明显;2)波浪冲击压强作用下码头面板内力的动力计算结果随着冲击压强频率的增大而迅速减小,当冲击压强频率大于80 Hz后,动力计算结果约为静力计算结果的0.2倍。

| Abstract: | The parameter language APDL of finite element software ANSYS was used to research the dynamic characteristics of pile-gravity wharf panel.The results show that: The dynamic and static calculation results of wharf panel's internal force is almost the same under the wave slowly varying pressure action,and the dynamic magnification coefficient of wave slowly varying pressure is not obvious;The dynamic calculation results decrease rapidly with the frequency of wave impact pressure increasing,when the frequency ... |
