浮箱拼组浮墩抗沉性的建模与仿真

Modeling and Simulation of the Anti-sinking Pontoons-Assembled Floating Piers

战时深水大跨桥梁损毁后,为尽快恢复交通通畅,可利用浮箱拼组成浮墩、浮桥和轮渡。以铁路深水浮墩为例,用ADAMS软件对浮墩的抗沉性进行了仿真,将仿真结果与理论计算值相比较,两者相差不大。浮墩的抗沉性仿真过程可为其遭受打击时的快速抢修提供参考。

In order to restore the smooth transportation when large-spanned bridges are clestroyea in wartime, we may assemble floating piers, barges and pontoon bridges with various pontoons. With deep-water railway floating piers as a practical example, a simulation analysis,with the help of the ADAMS software, is made of the anti-sinking performance of them. The difference between the simulated result and the calculated result is found very little. The simulation process may serve as a technical guidance for the rush-repair of large--spanned bridges when they are destroyed in wartime.
