摘要
以实际工程为背景,介绍了跨京广高铁转体桥梁的设计条件,上、下结构设计和球面转动体系的设计要点,以及现场施工情况。转体桥梁设计方案解决了交通运输繁忙的高速铁路跨线桥梁建设中的难题,与同等规模的其他桥型相比优势明显,安全可靠。
On the background of practical engineering, the design conditions, the design of upper and lower structures, the main points of the design of the spherical rotating system and the analysis of the structure are introduced. The design solution has solved the difficult problem in the construction of high speed railway overpass bridge with busy traffic and transportation. It has obvious advantages compared with other bridge types of the same scale, and it is safe and reliable.
