摘要
文章结合工程实例,根据同步顶升技术更换连续梁桥支座的施工要求,设计出不同的顶升施工方案,并分析各方案的优缺点,提出最终的优化方案及施工控制要点。
Combined with the construction practice and based on the construction require-ment of replacing the bearing of continuous box girder bridge with synchronous lifting technology,the article designs different lifting construction plans and analyzes advantages and disadvantages of each plan.A final optimal plan and construction key points are proposed in the end.
