【摘要】 在建立大型沉管隧道管节在水面浮运 (包括拖曳、顶推 )和管节自水面至水底沉放过程数学运动模型的基础上 ,运用有关试验数据和经验公式对管节运动过程中所涉及的外力进行了分析及估算 ,并数值模拟管节浮运和沉放运动过程 .最后采用计算机实时动画技术 ,对管节浮运和沉放运动实现计算机可视化更多还原

【Abstract】 Based on experimental data and empirical formula,governing equations of immersed tube tunnel element maneuvering and immersing are established,and the results of numerical simulation are also given.Finally,compter visualization programs of tunnel element movement are worked out by using VC ++ 5.0 language.更多还原
