Construction Design and Calculation of 0# Bracket for Continuous Girder of Xihe Grand Bridge

西河特大桥跨101国道连续梁采用悬臂浇筑法施工,其0#块采用墩顶托架法施工,该托架具有受力明确、安装简便、经济合理等优点。文章主要介绍了托架支撑系统的施工设计与检算,同时,对托架的施工安装进行了简要的阐述,对同类型桥梁的施工具有较好的指导作用。

The continuous girder of Xihe grand bridge across the national road No.101 is constructed by cantilever casting method.The 0#block of Xihe grand bridge is constructed by pier top bracket method.The bracket has the advantages of clear force,simple installation and reasonable economy.This paper mainly introduced the construction design and calculation of bracket support system,and briefly expounded the construction and installation of bracket,which has a good guiding role for the construction of similar bridges.
