摘　　要：介绍高赞大桥22#承台在采用大尺寸无底套箱施工时,利用钢护筒与混凝土之间的摩阻力克服封底后抽水时产生大浮力的不利因素,顺利完成承台从设计到实施的过程。For construction of No. 22 pier cap of Gaozan Bridge by means of large- size bottomless jackets, this paper mainly introduces a method which utilizes the friction force between steel liners and concrete to overcome adverse factor, i.e. big buoyancy generated during water pumping after the bottom is closed, and favorably completes the pier cap in the process from design to construction.
