Abstract
A curved multi-span flat-slab continuous rigid frame bridge crossing above five existing main lines of railway are taken as an example, and its scheme comparison, design standard, structure system as well as construction method are introduced in this article. By analyzing longitudinal and lateral performances with finite-element analysis software, it can be learned that the structure is safe and reliable. Because of the characteristics of multi-span and curve site, an innovative bearing layout scheme is adopted; side piers are hinged with flat-slab and the middle piers are consolidated onto flat-slab. Besides, full supports are applied in combination with falsework during construction, which can provide significant reference and application to the similar projects.关键词
