U型砼梁抗压力强、减震、隔音,具有节约建筑材料、安装方便、结构新颖、外形美观等特点.但因其结构砼壁薄,尤其在底板处,且为开口断面,因此抗扭刚度低.本文通过南京至高淳城际快轨项目的实际案例,对 U 型梁的架设吊装技术予以探讨.

The U-shaped concrete beams have many advanta-ges such as compressive strength, shock absorption, sound ins-ulation, saving building materials, easy to instal , novel struct-ure and beautiful appearance, but it has thin concrete wal stru-cture, especial y in the bot om plate, and the opening cross-se-ction, low tensional stif ness. In this article, the author explore-s the U-beam erection lifting technology bases on the actual c-ase of Nanjing to Gaochun Intercity Rapid Rail project.
