摘要
智能化升降式应急桥梁是一种应用于城市平交道口的钢结构装配式便桥,它采用箱形梁结构拼装而成,具有造价低廉、机动性强、装配速度快、缓解交通压力效果明显等优势。本文首先对升降式应急桥梁主要截面的应力和变形情况进行检算,再采用ANSYS进行仿真验算,通过与理论值的比较得出所设计升降式应急桥梁的安全性。
Intelligent lifting emergency bridge is a kind of steel structure assembled bridge that is applied to city level crossings. It is assembled by box-beam structure and has the advantages of low cost, strong maneuverability, quick assembly, and ease of traffic pressure. Firstly, the stress and deformation is evaluated for the main section of an elevating emergency bridge, and then the simulation software of ANSYS is used to carry out simulation verification. By comparing with the theoretical value, the safety value of the designed elevating emergency bridge is obtained.
