对龙河大桥0、1号块托架预压计算方法

Computational Method of No.0 and No.1 Block Bracket Preloading of Longhe Bridge

在桥梁施工中,连续刚构施工作为一种山区首选桥型在实际应用中非常广泛。其中,合龙段预压施工工艺又是连续刚构施工过程中很重要的一项技术。结合对龙河大桥0、1号块托架预压工程实例详细介绍预压计算方法及实施方案。为同类工程施工提供借鉴。

In bridge construction, the construction with continuous rigid frame structure is a preferred type of bridge in mountainous areas, which is widely used in practical applications. Among them, the preloading technique of the closure section is important during the construction. This paper introduces the computational method of preloading and the implementation scheme with the example of the No. 0 and No. 1 block bracket preloading of Longhe Bridge, which provides reference for similar engineering constructions.
