介绍了两种在提升桥梁净高的同时不增加桥梁上部结构自重的方法,然后以天津市八里台立交桥为例,对保持原有主梁的片数、减小梁高、尽量不改变原有主梁的尺寸的方法进行了详细的说明,分析了该方法的特点。最后建议在对既有桥梁进行换梁维修时尽量采用保持桥梁主梁片数、尽量不改变原有主梁尺寸的方案。

Two kinds of methods for increasing the clear height of bridge without the increasing of dead weight of bridge superstructer are introduced in the paper. Taking Balitai Interchange in Tianjin for an in?stance, the method of maintaining the original number of beams, reducing the height of beam, keeping the dimension of original beams is expatiated on. In addition, the characteristics of the method are analyzed. Finally, it is suggested that the scheme of keeping the number and the dimension of main beams should be adopted as far as possible.
