| 摘 要： | 文章探讨驳船吊挂沉放法进行沉管管段的沉放作业过程中,驳船升沉运动和波浪联合作用对沉管管段运动特性的影响。采用边界元方法求解作用在沉管管段的波浪力,驳船升沉运动考虑为简谐运动,应用四阶Runge-Kutta方法求解沉管管段的运动方程。通过数值算例分析,探讨了驳船做不同振幅与不同相位的升沉运动和波浪联合作用下沉管管段的运动特性。 |
| 关 键 词： | 驳船 升沉运动 沉管管段 运动特性 |

| Abstract: | In this paper,the effect of the barge heave motion and waves on the motion response of tunnel element in the immersing operation process was studied.The boundary element method was used to calculate the wave force on the tunnel element,and the fourth order Runge-Kutta method was applied to solve the motion equation of the tunnel element.The motion characteristics of the tunnel element under waves and the barge heave motion with different amplitudes and phases were analyzed by the numerical model. |
| Keywords: | barge heave motion tunnel element motion characteristic |
