| 摘 要： | 对遭受破坏桥梁进行剩余承载力分析是战时桥梁抢修中的首要工作。采用ANSYS软件建立了铁路客运专线32m箱梁的有限元模型，针对箱梁可能的破坏情况：翼缘板破坏、箱体局部炸穿和箱梁一侧范围炸坏，分析计算了破损后结构的剩余承载力，据此得出通车、限载限速和不能通车的结论。可为战时32m预应力混凝土双线简支梁的抢修恢复提供理论依据。

| Abstract: | The analysis of the residual capacity of bridges damaged is the first and foremost part of the bridge-rush-repair work at wartime.With the help of the finite element software ANSYS,established is the model of the 32 m box girder for passengers-oriented railways,by means of which the residual capacity of the damaged girder is analyzed and calculated,with damage done to different parts of the girder taken into account to aim at determining the residual capacity of the box girder after it is damaged in various... |
