摘要:
针对大跨度斜拉桥索梁锚固区构造复杂、受力集中的特点,采用大型有限元分析软件对锚箱式索梁锚固结构进行分析。由于在巨大索力作用下锚圈、垫板和锚箱承压板之间是紧压密贴的关系,传力方式是一种高度的结构状态非线性行为,所以计算中采用了接触非线性技术进行模拟,并与通常简化计算方法——等效板厚法做了比较,发现采用接触非线性技术能更真实地掌握锚箱各板件的应力状态和分布特点,最后为优化锚固区结构设计提出了一些建议。
Abstract:
The anchorage zones have complicated structures and endured huge cable force in long-span cable-stayed bridge. In view of this characteristic, the model of anchoring box style cable anchorage structure was studied by large-scale finite element analysis sofeware.Under giant tension function,there were close relations between anchoring circle, setting plate and bearing plate,and the way of power transmission was an distinct structure condition non-linear behavior.So in the computation,authors used contact non-linear technology carrying on the simulation and compared it with usual simplification computational method.Through using this technology,authors found that the actual stress state and distribution were received and the instructive conclusions for optimizing the anchorage zones structural design were drawn.
