摘要
以沪瑞高速公路北盘江大桥为工程背景,利用A nsys建立了正交异性钢桥面板的空间结构模型,针对三类不同临时车辆荷载工况,对正交异性钢桥面板的作用进行分析,给出临时车辆作业的限制条件,确保了施工过程中桥面板的结构安全。
Taking Beipanjiang Bridge in the Hu-rui Expressway as the project background, the software ANYSY is used to establish the spatial structure model of orthotropic steel bridge deck, the analysis is carried out for spatial structure model under three varied load modes of construction vehicles, the working restrictive condition of construction vehicle is given in according to the analysis result, it guarantees the safety of the orthotropic steel bridge deck in the construction process.
