桥梁球型钢支座全寿命设计及施工方法

Design and Construction Methods on Full Life of Bridge Spherical Steel Bearing

结合国内特大型跨江跨海桥梁施工中采用了球型钢支座的现状,依托东洲湘江大桥工程实体,对球型钢支座进行了全寿命设计,使其满足了使用寿命及承载力要求。并针对安装质量要求,提出了一整套施工工艺流程,为同类工程支座安装提供参考。

Based on the present situation of the spherical steel bearing in the construction of the large cross river cross sea bridge in China, the full life design of the ball type steel bearing was carried out by relying on the engineering entity of the Xiangjiang bridge in Dongzhou, so that it meets the service life and the requirements of the bearing capacity.Aiming at the installation quality requirements,a set of construction process was put forward to provide reference for the installation of similar engineering supports.
