潼湖特大桥跨潮莞高速(88+160+88)m连续刚构关键施工技术

Key construction technology of(88+160+88)m continuous rigid frame for Tonghu super large bridge crossing Chaoguan expressway

随着交通的日益发展,大跨度跨线连续刚构桥梁修建越来越多。本文结合潼湖特大桥跨潮莞高速(88+160+88)m连续刚构施工的成功实践,详细阐述了该桥的施工关键及其梁体施工的线型控制,跨既有公路施工防护及混凝土施工等关键施工技术,可供类似工程参考。

With the development of traffic,more and more long-span continuous rigid frame bridges have been built.Combined with the successful construction practice of(88+160+88)m continuous rigid frame for Tonghu super large bridge crossing Chaoguan Expressway,the key construction technologies of the bridge,such as the linear control of the beam construction,the construction protection for the existing highway,and the concrete construction,were expounded in detail,which can provide reference for similar projects.
