大跨度斜拉桥彩针形钢独塔施工技术
|
摘要
目前我国斜拉桥的建造技术已经处于世界领先水平,已建成斜拉桥的数量也位于世界前列,但塔墩铰接的彩针形钢独塔斜拉桥应用实例较少。此类型桥施工方法有多种,包括支架+吊装法、转体法等。以上海市惠平路蕰藻浜大桥为例,结合桥梁的具体位置状况、操作的难易程度和经济性对每种施工方法进行评价,最终采用逆向竖转的方法,并对关键施工技术进行了介绍。实践证明,施工效果良好,可供类似项目借鉴。
Right now, the construction techniques for cable-stayed bridges of our country play a leading role in the world, and the number of completed cable-stayed bridges in our country also takes its place in the front ranks of the world. However, the number of the practical examples of tower-hinge-connected-to-piers cable-stayed bridges with single-tower of colored needle-shaped steel is comparatively little. There are quite a few construction methods for such types of bridges, which include the brackets+lifting method, the rotating method, etc. With the Yunzaobang Bridge at Huiping Road in Shanghai as a practical example, comments are made in the present paper on various construction methods as regard to the specific locations and circumstances of the bridges, the difficulty in the operation of each method and the economy of each method, upon the basis of which the Reversion-Vertical-Rotation Method is finally adopted for the project, with the key construction techniques of the method dealt with in detail in the paper. It may serve as a useful reference for other projects of similar types.
