自锚式斜拉—悬索混合体系桥梁施工过程力学行为研究
|
摘要
大跨径桥梁多为缆索承重桥梁,考虑到悬索桥和斜拉桥均有各自明显的特点,于是出现了结合二者优点的新桥型—自锚式斜拉—悬索混合体系桥梁。自锚式斜拉—悬索混合体系桥梁不同于传统韵斜拉桥和悬索桥,结构体系复杂,目前还没有已建成的实例。本文主要针对自锚式斜拉—悬索混合体系桥梁的施工过程进行试验研究和探讨,具体工作和研究成果如下:
(1)本文根据现有的研究成果和国内外相关的文献,在悬索桥分析理论、斜拉桥分析理论、桥梁结构非线性分析理论及非线性有限元方程计算方法的基础上,归纳概括了自锚式斜拉—悬索混合体系桥梁的基本分析理论和计算方法。
(2)在自锚式斜拉—悬索混合体系桥梁基本分析理论的基础上,采用MIDAS/Civil通用有限元计算程序,针对施工阶段试验模型建立有限元计算模型,并模拟实际施工步骤,对模型桥的各个施工工况进行结构分析。
(3)在模型施工阶段试验的基础上,对比和分析模型试验结果、实桥设计换算结果及模型有限元计算结果,研究自锚式斜拉—悬索混合体系桥梁在各相应工况下的结构整体受力性能、变形情况及安全状况。
In recent years,with the rapid development of transportation,the long-span bridge construction has been entering a period of new development.More of the long-span bridges are cable-supported bridge,as suspension bridge and cable-stayed bridge obviously have their own advantages and disadvantages,a new combined structural system bridge called self-anchored cable-stayed suspension system-combined bridge comes out.This type of bridge has both merits of self-anchored suspension bridge and cable-stayed bridge, but its mechanical properties are more complicated and different from them and there is no such bridge style constructed in the world at present.This paper mainly gives the testing study and discuss about the course of construction of self-anchored cable-stayed suspension system-combined bridge,and its work and research results are as follows:
(1)Based on existing research results and the relevant literature at home and abroad, which include the theory of suspension bridge, cable-stayed bridge, and non-linear structure, the paper summarizes the theory of self-anchored cable-stayed suspension system-combined bridge.
(2)Based on the theory of self-anchored cable-stayed suspension system-combined bridge and the finite theory, the paper establishes finite calculation model about the bridge construction model test by using the general finite element computational software MIDAS/Civil, and analyses the model structure with simulating the construction steps.
(3)Based on the construction steps of the model test, the paper analyses the mechanical performance, alignment, and security circumstance under the bridge construction.
