几种连续箱梁0#段施工托架分析

Analysis of Construction Brackets for Several Continuous Box Girder 0# Sections

随着国内经济的快速发展,桥梁技术也随着突飞猛进,大跨度连续箱梁在铁路、公路以及市政工程出现的频率越来越多,连续箱梁中的0#段是整个箱梁的关键部位,其施工也显得尤为重要,而托架则是0#段施工中的关键组成部分,本文就常见的几种托架从结构类型、结构特点、施工过程、经济利益进行了深入分析。

With the rapid development of the domestic economy, the bridge technology has also advanced rapidly. The large-span continuous box girder is more and more widely used in railways, highways and municipal projects. The 0# section in the continuous box girder is the key part of the entire box girder, so its construction is also very important, and the bracket is a key component in the construction of 0# section. In this paper, several common brackets are analyzed in depth from structural type, structural characteristics, construction process and economic benefits.
