摘要
依托连续钢箱梁高架桥项目,介绍了连续钢箱梁主要病害成因,并在此基础上对连续钢箱梁优化设计提出了改善方法,最后针对该项目的顶推施工方法,分析顶推施工过程中的受力情况,结果表明顶推施工过程中,钢箱梁的结构受力均满足要求.
Based on continuous steel box girder viaduct project,the main causes of the diseases of the continuous steel box girder viaduct are introduced,and the optimization designs of incremental launching construction method are put forward. Force bearing status in the incremental launching construction is analyzed. The results show that the structure of the steel box girder meets the requirements in construction.
