大跨径连续桥梁施工技术探讨

Discussion on construction technology of long-span continuous bridge

针对在当前快速发展的桥梁建设行业中广泛应用的大跨径连续梁结构,结合现有研究资料对这种全新结构体系的受力情况和特点进行分析介绍,以此为基础提出它的施工工艺和特点,包括基础、索塔和上部结构三个方面,并根据保证结构质量与安全的基本需要,提出在大跨径连续梁桥施工中需要高度重视和加强的施工技术控制,即应力控制、线形控制、稳定控制和安全控制,以此为实际的大跨径连续桥梁施工提供可靠的技术支撑。

In view of widely used large span continuous beam structure in present quickly development of bridge construction industry,the force and characteristics of this new structure are analyzed and introduced. On this basis,combining with present research data analyzed and introduced the force situation and characteristics of this new structure system,based on this proposed its construction technology and characteristics,including the foundation,cable tower and superstructure three aspects,and according to the basic needs of ensuring the structure quality and safety,proposed should pay high attention to and strengthen the construction technology in long-span continuous bridge construction,that is,stress control,linear control,stability control and safety control,so as to provide reliable technical support for large span continuous bridge construction.
