双线铁路连续钢箱梁桥方案设计和静动力计算分析
|
摘要
大跨度连续钢箱梁是目前比较流行的桥梁形式,尤其在公路交通中使用非常广泛；目前,连续钢箱梁桥在铁路桥梁中尚没有得到实际应用。随着钢铁事业的发展,连续钢箱梁在铁路交通中也有很好的前景。
论文首先回顾了连续钢箱梁桥在国内外的发展及结构特点。以嘉陵江大桥为工程背景,提出了主跨180m的连续钢箱梁桥的设计方案。采用大型有限元计算软件Midas/civil建立基于梁单元的全桥组合模型,详细分析了双线铁路连续钢箱梁桥的各施工阶段主梁、桥墩的受力和变形；通过梁单元模型计算,分析运营阶段列车活载、风荷载、整体温差、梁截面温差、制动力及横向摇摆力等不同作用及组合下桥梁的响应；研究连续钢箱梁的动力特性,利用子空间迭代法计算出桥梁的自振频率及振型；通过反应谱法和时程分析法对桥梁结构进行了抗震计算,得出相应结果；分析施工阶段、成桥阶段及运营阶段的桥梁弹性稳定性,得出桥梁的安全稳定系数及相应的模态；作者还利用大型有限元软件Algor建立了以板单元为主的主梁模型,在恒载和活载作用下进行详细应力分析,得出钢箱梁顶底板、腹板及纵梁等杆件详细分析结果。
通过上述分析,作者比较全面地了解了连续钢箱梁桥的静力和动力特性,并相应掌握了运用大型有限元软件分析计算桥梁的方法。
A continuous box-girder bridge with a long span is very popular in highway bridge construction work; although the same stytle isn't existed in railway bridge, we still believe that it has a bright future as the development of steel construction.
The thesis firstly reviews the domestic and international development and summaries the structural characteristics of continuous steel box beam. Based on the plan of the Jialing River Bridge, the conceptual design of a continuous box-girder bridge with 180 meters-mainspan is proposed. A combined finite element model involving beam element for the bridge is developed by using Midas/civil, which is a general commercial finite element software. Stress and deformations of the beam and piers are analyzed incrementally following the construction stages. Based on the result of the finite element model, we examine the static load cases' behavior including live train load, wind load, temperature variations, braking force and the horizontal sway force of the train and combinations of these loads at operational stage. Dynamic analysis are carried out, free vibration modes and frequencies of the bridge are included in the term of subspace iteration method. Using response spectrum method and time history method, we study the seismic design of the bridge and compare the results. Analysising the elastic state of equilibrium in different states, we can include the safety of the bridge. Afterward, a finite element model involving brick and plate element for the bridge is developed by using Algor, a general commercial finite element software. Detail stress analysis on top slab, base slab, web, longitudinal beam and other parts are included in dead load and live load cases.
Therefore, the static and dynamic performance of the bridge with a continuous steel box beam is comprehensively understood, and the analyzing method of bridge is conceived.
