深圳空港新城展览大道景观钢桥施工方法研究

深圳空港新城展览大道景观桥是一种新型景观钢桥结构。因其造型独特,拱肋在结构体系转换前的稳定性较差,常见的“先拱后梁”或“先梁后拱”的施工方法都无法很好地解决施工安全性和经济性的矛盾。为此,尝试在上述两种方法的基础上,利用主纵梁、横梁及桥面的结构特点,采用拱、梁交叉施工的方法,在保证施工安全性的前提下,较好地解决了这一难题,可为今后类似工程的施工提供参考。

Research on Construction Method of Landscape Steel Bridge in Exhibition Avenue of Shenzhen Airport New City

A landscape bridge in Exhibition Avenue of Shenzhen Airport New City is a new type of landscape steel bridge structure. Because of its unique shape, the stability of arch rib is poor before the structural system transformation. The common construction methods of "arch before beam" or "beam before arch" can not solve the contradiction between the construction safety and economy. Therefore, on the basis of the above two methods, this paper attempts to use the structural characteristics of the main longitudinal beam, cross beam and bridge deck are attempted to use, and the method of arch and beam cross construction is used. On the premise of ensuring the construction safety, this problem is better solved, which can provide a reference for the construction of similar projects in the future.
