斜靠式钢拱桥施工分析

Construction analysis of leaning-type steel arch bridge

通过采用MIDAS软件分析了一座斜靠式钢拱桥的各阶段的受力特性,对该桥梁的实际施工过程进行了模拟,分析了施工时临时支撑的设置引起脱空现象的原因,通过分析该模型结构,说明了应重视桥梁的施工方法及对施工实际的仿真模拟。

Utilizing MIDAS software the mechanic characteristics of one leaning-type steel arch bridge in various stages are analyzed. In addi tion construction process of this bridge is simulated. In view of the bearing hanging phenomenon caused by temporary support analysis is made Through analysis structure of model. Author points out that construction method and analog simulation of bridge should be paid more attention.
