桥梁预应力工程施工难点及技术对策

Construction difficulty and technical countermeasure of the pre-stressed bridge project

以京津城际轨道交通工程北京环线特大桥跨五环连续梁桥为例,重点阐述了桥梁预应力工程施工难点,并针对施工难点提出了施工技术对策,为类似项目提供技术参考。

Make the exceptional bridge which is the bridge spanning five continuous beams in the loop road of Beijing city in the orbital traffic project between Beijing city and Tianjin city an one example, it represents the construction difficulties of the pre^stressed bridge project importantly, and brings forward technical countermeasures of construction aiming at the constructions difficulty, which will supply reference to the similar items.
