摘要
利用大型商用有限元软件Midas/Civil对牛湾大桥进行整体建模,研究了在船舶撞击下的结果安全性.根据船舶撞击力的合理取值,在合理模拟边界条件的前提下,分析了支座、预应力效应和汽车荷载等因素对大桥结构安全性的影响.
The structural safety of the Niuwan Bridge subjected to vessel collision is investigated by the large-scale commercial finite element softwear Midas/civil. A whole FEM model is built and a reasonable analysis and illustration for taking the value of vessel-collision forces is presented. Additionally, under the premise of reasonable simulation of the boundary conditions, the effects of the support abutments, the prestressing and the carloads are considered.
