摘要
保证桥梁在汛期的施工进度,确保河道导流工程质量、环保目标的实现,潮白河大桥在桥梁下部结构施工的同时采用桩膜法分期修建围堰,通过对围堰的抗倾倒计算和结构抗滑移计算,得出围堰的建设标准和施工工艺流程可行,抗倾覆满足安全要求,且缩短了施工工期,节约了大量的人力、物力,降低了成本.
Abstract
In order to ensure the construction progress of the bridge during the flood season and the achievement of the quality and environmental protection goals of the river diversion project,the Chaobai River Bridge adopts the pile membrane method to construct cofferdams in stages while constructing the lower structure of the bridge.Through the calculation of the anti overturning and structural anti sliding of the cofferdams,the construction standards and construction process of the cofferdams are feasible,the anti overturning meets safety requirements,shortens the construction period,saves a lot of manpower and mate-rial resources,and reduces costs.
