以某双柱式桥墩维修加固为工程背景，通过对桥梁病害及成因进行检测和分析，得出了桥下大方量填土是导致墩柱水平环向裂缝、不均匀偏位和盖梁扭转破坏的根本原因。基于该桥下部结构病害严重且其承载能力不足，对维修加固方案进行了比选和探讨，最终采用了安全可靠、经济实用的维修加固方案。
以某雙柱式橋墩維脩加固為工程揹景，通過對橋樑病害及成因進行檢測和分析，得齣瞭橋下大方量填土是導緻墩柱水平環嚮裂縫、不均勻偏位和蓋樑扭轉破壞的根本原因。基于該橋下部結構病害嚴重且其承載能力不足，對維脩加固方案進行瞭比選和探討，最終採用瞭安全可靠、經濟實用的維脩加固方案。

In this paper,taking double-column pier maintenance as the engineering background, through the testing and analysis of diseases and causes of the bridge,it is found that the basic reason of pier horizontal cracks,uneven deviation and capping-beam damage is generous amount of filling soil.Due to serious disease of substructure and its insufficient bearing capacity,through comparison and discussion about the bridge maintenance scheme,the safe,reliable,economical and practical scheme was adopted at last.
