高墩柱现浇混凝土连续箱梁支架的选择与施工控制

Selection and Constructional Control of Supports for Cast-in-Situ Concrete Continuous Box Girders on High Columns

通过对各种类型的高墩柱箱梁现浇支架材料、结构及其特点、适用条件的介绍,对高墩柱混凝土连续箱梁现浇支架的选择进行了综合阐述。并从支架预压和预拱度控制两个方面,对支架施工控制作重点探讨,对桥梁工程具有一定的参考价值。

Based on the introduction to various types of materials and structures as well as the features and applicable conditions of the supports, the selection of the cast-in-situ concrete supports for concrete continuous box girders on high columns is com- prehensively expounded and the discussions focus on the control of the construction of the supports from the aspects of preloading and camber of the supports, providing reference of a certain value for bridge works.
