分幅式钢箱梁斜拉桥空间受力研究
|
摘要
斜拉桥是高次超静定结构,受力较为复杂。而随着斜拉桥由单幅发展为双幅,由于箱梁幅数的增加必然致使两幅箱梁之间产生必要的横向连接,这将使双幅斜拉桥部件间的横向影响较为突出,横向受力也变得较为复杂。同时由于箱梁幅数的增加也将致使斜拉索索面的增加,双幅斜拉桥的横向空间受力特性也显得尤为明显。对双幅多索面斜拉桥进行精确的空间性能研究,明确其空间的受力特性将有利于双幅多索面斜拉桥达到合理的成桥状态,同时也对双幅多索面斜拉桥的设计、施工及施工监控工作起到更好的指导作用。由此可见对双幅多索面斜拉桥的横向空间性能进行研究具有重要的理论及工程应用价值。论文主要进行如下研究工作：
(1)分别研究分幅吊装与整体吊装中不对称吊装对主梁、主塔等的影响,确定四索面分幅式斜拉桥的最优吊装方案。
(2)提出内外侧索力分配的四种方案,研究四种方案中主梁应力、横梁应力、索塔应力、索塔偏移及梁段横坡的变化,并最终确定最优的内外侧索力分配方案。
(3)利用有限元分析软件MIDAS建立空间模型,研究嘉绍大桥永久横梁的最佳安装时机及临时横梁的最佳拆除时机。
The cable-stayed bridge is an indeterminate structure with high degrees and its force is more complex. The cable-stayed bridge is developing from single desk to double desk. The increase of the number of box girder inevitably results in the necessary cross-linking between the two box girders, so that the components of cable-stayed bridge with twin desks is more prominent and its transverse force becomes more complicated. Due to the increase in the number of box girder will result in the increase of cable plane, the force characteristics of cable-stayed bridge with twin desks is Particularly obvious. Study for the sPatial properties of multiple cable plane cable-stayed bridge with twin desks precisely and pecial mechanical characteristics will be conducive to multiple cable plane cable-stayed bridge with twin desk, making it a reasonable state. Moreover, multiple cable plane cable-stayed bridge with twin desk will be better guided in terms of design, construction and construction monitoring work. This shows that the study of multiple cable plane cable-stayed bridge with twin desk contains great theoretical and engineering application value. The thesis mainly focuses as follows:
(1) The effect of asymmetric lifting in the framing lifting and the overall lifting to the girders and the main tower was studied respectively. And the optimal lifting program of cable-stayed bridge with four cable planes and seParated twin-decks was raised.
(2) The four scheme was proposed for the inside and outside cable force distribution. The change of stress in main girder, crossbeam, tower, tower offset and the change of transverse slope in beam are studied in the four scheme so as to ultimately make the optimal scheme for the inside and outside cable force distribution.
(3) The finite element sPace model was built up by MIDAS/Civil to study the optimal time of installation and dismantling of temporary beams of Jia Shao Bridge.
