摘要
本文以重庆长寿长江公路大桥为工程背景,主要以斜拉桥的几何非线性问题对桥梁结构的影响进行分析研究。在介绍了斜拉桥几何非线性分析的基本理论的基础上对影响斜拉桥几何非线性的三个主要因素(大变形效应、斜拉索垂度效应和弯矩轴力的组合效应)进行了深入的阐述。并采用大型通用软件MIDAS/Civil针对长寿长江公路大桥建立有限元模型,对施工阶段的几个特殊工况分别进行线性与非线性计算并对结果进行比较分析得出相关结论。
此外,本文在探讨斜拉桥施工中索力的控制方法的基础上对长寿桥的斜拉索初始张拉力进行了确定;同时对前支点挂篮主要构造特点和受力平衡关系进行了详细的分析,提出了斜拉索中间索力的确定方法,并以重庆长寿长江公路大桥工程为依托项目进行了斜拉索中间索力的允许范围以及合理索力值的计算。
This thesis focuses on geometric nonlinear static analysis of long-span cable-stayed bridges. The basic theories of geometric nonlinear analysis about long span cable-stayed bridge are introduced. Then three principle factors that affect geometric nonlinearity of cable-stayed bridges are described, which are large displacement, effect of cable sag and combined effects of moment and axial force; then the finite element methods are introduced separately. And then, the finite element model of Chongqing Changshou Yangtze River Highway Bridge according to its scheme with single pylon is erected by MIDAS/Civil, a general finite element software. In this thesis presents the methods to simulate the real load-bearing condition of bridge structure, effects of cable sag and erecting and removing of element under construction stages. At last, the linear and nonlinear analysis of construction stages is made. According to the comparison between those results, conclusions aredrew.
In this paper, the Rational Cable Force of Chongqing Changshou Yangtze River Highway Bridge were claimed on the basis of the control method about the construction of the cable-stayed bridge. At the same time, we pay more attention on the analysis of the main characteristics and the structure balance of the former stronghold cradle. And raise the method of the middle Cable Force of Cable-stayed Bridge. In the end, we give out the right middle Cable Force of Chongqing Changshou Yangtze River Highway Bridge base on the method we just introduce.
