摘要
以沈阳市东一环高架桥建设经过的一个重要节点—一座已建成的人行天桥为工程背景,介绍了为配合高架桥建设移动其主桥桥墩,进行托梁换柱的合理改造方案的确定。
The thesis takes a built - up pedestrian overcrossing which is an important node that the Viaduct of East First Ring has passed as engineering background. To complete the viaduct, the main bridge pier has to be moved. Thus a reasonable modification scheme of relocating its column while keeping the trimmer beam stable has to be confirmed and the thesis gives a comprehensive analysis on it.
