斜拉桥施工过程的仿真计算与分析

Simulation and analysis of construction process for the cable-stayed bridge

以石家庄仓安路斜拉桥施工过程为研究背景,利用有限元分析软件ANSYS,实现了斜拉桥施工过程的模拟计算.得到的计算结果表明,该方法可使成桥后主梁的线形和结构的内力得到合理控制,从而有效地确定斜拉桥的合理施工状态,为今后同类斜拉桥的设计和施工提供参考.

In this paper, a simulative computation is realized of the construction of the cable-stayed bridge at Cang＇ an Road of Shijiazhuang city through the finite element analysis software ANSYS. The result shows that the method call effectively control the alignment of the main girders and the internal force of the bridge structure after the bridge construction, and thus it can efficiently determine the rational construction. With its practical value, it may provide references for the design and construction of similar cable-stayed bridges.
