| 摘 要： | 为考察不同风速、波高时高架栈桥在风浪耦合作用下的位移特性,采用分离涡方法和任意拉格朗日-欧拉方法(ALE arbitrary lagrangian eulerian)求解栈桥系统的流固耦合位移响应.结果表明:风对栈桥所受风浪耦合荷载大小影响较大,高架栈桥的位移随风速增加而增大.波浪主要增加栈桥的往复振荡,同时,波浪对桥...

| Abstract: | To analyze the displacement response of the overhead trestle bridge subjected to different wind speeds and wave heights,the DES(detached eddy simulation) method and ALE(arbitrary Lagrangian Eulerian) method were employed to solve the response of the trestle bridge system during the fluid structure interaction.Results show that the wind mainly affects the wave loads on the trestle,and the higher the wind speed,the larger the displacement response; that the wave mainly increases the trestle's oscillation,and ... |
