铁路钢结构斜交便桥轨道变形病害的分析

Analysis on track deformation defects of temporary skew steel structure bridge on the railway

以某钢结构斜交施工便桥为例,应用Midas/Civil建立了三维立体模型,研究了在列车荷载作用下便桥上轨道的竖向变形情况,并针对这种病害提出了相应的防治措施,以确保行车安全。

Taking the temporary skew construction bridge with steel structure as an example, the paper applies Midas/Civil to establish three-dimension vertical model, studies the vertical track deformation conditions of the temporary bridge under the train load, and puts forward corresponding preventive measures, with a view to guarantee the driving safety.
