介绍武广客运专线新建武汉站工程2000t级大截面鱼腹式箱梁结构设计特性.重点阐述鱼腹式箱梁模板设计、制作、安装、板面处理及模板拆除等关键技术；并通过采用有限元计算软件模拟大截面鱼腹式箱梁模板在施工中的实际工况,对模板设计结构进行了优化,以实现安全、经济的目的.工程实践证明,2000 t级大截面鱼腹式箱梁模板设计与施工技术有效地保证了工程施工质量.%This paper introduces the structure characteristics of the formworks of 2 000 tons large cross-section fish-bellied box girder of new Wuhan Station in Wuhan - Guangzhou Passenger-dedicated Line, especially focuses on the key technologies of the formworks of fish-bellied box girder including design, production, installation, surface treatment and removal etc. The finite element software was used to simulate the practical conditions of the formworks in the process of construction and optimize the formwork structures for the purposes of safety and good economic benefit. The engineering practice proves that with above technologies of design and construction of the formworks, the construction quality of the project can be ensured.
