【摘要】 大跨度连续梁一般采用挂篮悬臂浇筑施工,其关键技术为0号块墩顶的抗倾覆设计、0号块支架搭设与混凝土浇筑施工、挂篮的设计施工、结构体系的转换与合拢、线形控制等。该文以通榆河大桥施工为背景,详细介绍了上述相关技术,可为今后类似桥梁的施工提供一定的借鉴。更多还原

【Abstract】 The long-span continuous beam is generally constructed by the travelling form cantilever pouring method. Its key technique is the upsetting resistant design of No.0 pier top, the bracket erection and the concrete pouring construction of No.0, the design and construction of travelling form, the transforming and closing up of structural system, and the linear control. The article introduces in detail the above relative techniques through the construction of Tongyu River Bridge, which can provide some reference for the construction of the similar bridges in the future.更多还原
