摘 要: 各种大跨径桥梁的迅速发展使得对施工过程的仿真分析和控制日益重要。以淡水河特大桥为背景,介绍了大跨度桥梁施工过程仿真分析的目的和意义,通过建立有限元模型,分析了悬臂施工中影响预拱度的各项因素,为类似结构桥梁的施工控制分析提供参考。 The rapid devel opment of various kinds of long -span bridges makes the simulation analysis and control of construction process become increasingly important.In this paper,we introduce the intention and significance of the simulation analysis in the construction process of the long-span bridges.By a finite element model basing on the Dan-shui river long-span bridge,we analyze the factors which impact the pre-camber in the cantilever irrigating construction. Consequently,it provides a reference to analyzing for the construction control of the similar bridges.
