大秦线桥梁圆柱形高墩加固技术初探

On exploration for column type and high pier intensification technique along Datong-Qinhuangdao railway

以大秦线滦河特大桥加固为例,简要介绍采用连接两个桥墩托盘和墩帽的方法,使其成为框架结构,指出该加固技术既可有效增加桥墩的横向刚度,又提高了桥墩的基础稳定性,应用前景广泛。

Taking the intensification of Luanhe super-large Bridge along Datong-Qinhuangdao railway as the example, the paper introduces the method of connecting the two pier tray and pier hat, points out the intensification technique is the frame structure, which can increase the horizontal stiffness of the pier, and improve the foundation stability of the pier, so it has extensive future.
