由林李公司设计的诸暨市浣纱大桥,为独塔单承载面板拉桥,桥跨为2×65.35m,桥宽28m。上部结构由箱梁、拉板与塔柱组成,塔、梁、墩固结。该桥特点是采用单承载面、由刚性拉板代替柔性斜拉索,致使拉板在荷载作用下,应力变化幅度小,不存在拉索的疲劳等影响。且拉板由三对板代替单一整体板,不仅具有良好的景观效果,而且使结构受力更趋合理。该桥在国内外已建成的同类型桥梁中,桥宽属最大,多拉板式桥型属首例,本文扼要介绍了浣纱大桥的桥型选择、设计构思、与计算要点等。
Designed by the forest company Zhuji City Hanyu Bridge, a single tower for the single bearing panel, spanning 2 × 65.35m, bridge width 28m. The superstructure consists of box girder, pull plate and tower column, tower, beam and pier consolidation. The bridge is characterized by a single bearing surface, the rigid plate instead of flexible stay cables, resulting in the role of the plate under load, the stress changes in small, there is no cable fatigue and other effects. And the pull board by three pairs of boards instead of a single whole board, not only has a good landscape effect, but also make the structure more reasonable force. The bridge in the same type of bridge has been built at home and abroad, the bridge is the largest, Dora slab bridge is the first case, this article briefly describes the Huan Sha Bridge Bridge type selection, design concepts, and calculation points.
