摘要
大跨度预制梁具有重量大、预制难度大、吊装危险性大的特点。以广东梅子坝大桥50 mT型梁施工为例,详细介绍大跨度预制梁预制、运输、安装等施工关键技术。实践证明,这些施工技术与方法是可行的,可供同类工程借鉴。
Large-span precast beams are characterized by large weight, lots of difficulties in precasting and great danger in hoisting. Taking the 50 m T-beams＇ construction in Guangdong Meiziba Bridge as an example, this paper describes in detail the key construction technique of large-span precast beams in precasting, transportation and installation. Practice proves that the construction technique and methods presented are feasible, and thus may serve as a reference for similar projects.
